I'm a total beginner when it comes to soldering, and recently I've been trying (and failing) to solder together a simple circuit I put together for a Raspberry Pi sensor.
Although it works fine on the breadboard, when I solder it onto one of my perfboards, the sensor no longer turns on.
Here is a topdown view of my soldered circuit:
Here is a view of the connections (the red block is just covering up old connections from past attempts):

I think I see a few cold solder joints. But don't worry about that. (Could just be me.) However, are you treating that board as if it were a solderless breadboard? I'm not seeing much by way of connections anywhere.

@Lundin +1 for that. As a newbie, it's easy to get a bad joint. And on a larger board (when you get a little better), it's easy to miss soldering a pad, especially if you've made a homebrew PCB which doesn't have through-hole plating so you have to solder top and bottom sides of pins. You need to be really confident in your assembly skills before you can stop buzzing the connections through. And BTW for the OP, when buzzing connections through, print off the schematic and run a highlighter marker along each line as you buzz that connection, so you can check you've covered everything.

Everyone here is right. The perf board you are using does not contain the connections between pads like the bread board. If you got rid of the solder mask you would see something like this:
You have to make the connections manually or buy this type of perf board. Notice how it has the connections made in copper?

You actually did a good job on the soldering
The problem is that the board you are using, unlike the breadboard, has no connection for a given row of pads. You have to add wires or solder shorts on the back to make the connections you want.

A perfboard is not like a breadboard. A perfboard is called so, because it has holes in it, it is perforated!
So the whole perfboard contains only holes and no connections between any holes (unlike the breadboard). You have to interconnect the holes yourself.
In this case, you have to connect the two leads of the resistor to two jumpers. The first step is to solder every individual component on the perfboard. You did this step correctly!
Second step is to make connections between the soldered leads. In this case, you have soldered two resistor leads and two jumper leads. To connect leads together, you have to solder another wire between them, or you can just use a solder joint between them, i.e., connect the two leads only using solder.
The purple lines represent the connections you should make, i.e., the wires you should place externally to connect the required perfboard pads:
This is how you can connect adjacent holes using solder bridges. Source: How to make traces on an universal PCB?. Look at the answer by JYelton.
Also, you can use wires to solder holes together like this - Source: How to make traces on an universal PCB?. Look at the answer by Passerby.

The board you are using has no connections between the pads - you have to add wires between the pads to complete your circuit.
Also, you have excessively long leads sticking out of the pads on the solder side of the board - this could lead to unwanted connections (short circuits) between points in your circuit.

I think you are treating the perfboard as a breadboard. There is no connections between the points you have soldered.
This is how a breadboard looks. There are connections inside and you just have to pin in your wires. When you want to solder a perfboard you will have to make a connection using a wire like this:

Ya like everyone is saying you need to connect the components since it is not a bread board. I've found solar panel bus wire works really well as traces on these boards since it can get soldered directly onto it.

@ShapeOfMatter it gives you a nice place to put down through-hole and DIP things in a nice tidy way without having to fabricate a "real" board, you get the flexibility of free routing instead of five-in-a-row, and less parasitics.

@ShapeOfMatter: in my short experience toying with circuit making, a while ago, I've never seen anything like a preconnected perf board and my instinctive reaction has been exactly the opposite of yours: "What is for? Why someone in his right mind would spend money on that?"

You actually did a good job on the soldering
The problem is that the board you are using, unlike the breadboard, has no connection for a given row of pads. You have to add wires or solder shorts on the back to make the connections you want.

A perfboard is not like a breadboard. A perfboard is called so, because it has holes in it, it is perforated!
So the whole perfboard contains only holes and no connections between any holes (unlike the breadboard). You have to interconnect the holes yourself.
In this case, you have to connect the two leads of the resistor to two jumpers. The first step is to solder every individual component on the perfboard. You did this step correctly!
Second step is to make connections between the soldered leads. In this case, you have soldered two resistor leads and two jumper leads. To connect leads together, you have to solder another wire between them, or you can just use a solder joint between them, i.e., connect the two leads only using solder.
The purple lines represent the connections you should make, i.e., the wires you should place externally to connect the required perfboard pads:
This is how you can connect adjacent holes using solder bridges. Source: How to make traces on an universal PCB?. Look at the answer by JYelton.
Also, you can use wires to solder holes together like this - Source: How to make traces on an universal PCB?. Look at the answer by Passerby.

The board you are using has no connections between the pads - you have to add wires between the pads to complete your circuit.
Also, you have excessively long leads sticking out of the pads on the solder side of the board - this could lead to unwanted connections (short circuits) between points in your circuit.

I think you are treating the perfboard as a breadboard. There is no connections between the points you have soldered.
This is how a breadboard looks. There are connections inside and you just have to pin in your wires. When you want to solder a perfboard you will have to make a connection using a wire like this:

Ya like everyone is saying you need to connect the components since it is not a bread board. I've found solar panel bus wire works really well as traces on these boards since it can get soldered directly onto it.

I think I see a few cold solder joints. But don't worry about that. (Could just be me.) However, are you treating that board as if it were a solderless breadboard? I'm not seeing much by way of connections anywhere.

@Lundin +1 for that. As a newbie, it's easy to get a bad joint. And on a larger board (when you get a little better), it's easy to miss soldering a pad, especially if you've made a homebrew PCB which doesn't have through-hole plating so you have to solder top and bottom sides of pins. You need to be really confident in your assembly skills before you can stop buzzing the connections through. And BTW for the OP, when buzzing connections through, print off the schematic and run a highlighter marker along each line as you buzz that connection, so you can check you've covered everything.
