It's a bit hard to see exactly whats going on, but it looks like you've put the earth for the bridge to the back of the neck vol pot, I normal earth to the back of the same pot the hot wire is going to. That shouldn't really matter as you have a bridge between the backs of those two. So I'm wondering if it's just a dodgy solder joint somewhere. There is a lot of solder in these images, I'd probably just go over all of it and make sure there are good connections where there should be and no accidental connections, such as the neck hot wire possibly being shorted out by some stray solder.

Hopefully there will be some other eyeballs along who may be able to pick up any glaring errors I've missed.
