I suggest some more practicing soldering. There is a lot of solder, excess component leads and wires. I guarantee you that somewhere on that board, there is an unwanted connection. But without a schematic and better pictures (flip one side so the components on the top and the connections on the bottom are aligned between the two pictures.

Understood.
If the schematics look correct, then yes you must be right.

 

If the schematics look correct

Not picking on you, but those aren’t schematics. They’re pictures of a non-functioning board. It is nearly impossible to see how the circuit is wired or supposed to be wired from a picture.

THIS is a schematic. Not for your circuit but an example of what a schematic looks like. If your circuit is from an article there is likely a schematic in the article.

Right. Should’ve said perfboard design.
