I would reflow all of your solder joints. The solder joint to the ground in the power jack in particular looks like it might be a bit dodgy.
Other than that, I don't see any obvious issues. Your EL caps and transistors are oriented correctly, off-board wiring looks like it's connected correctly. Could be a lot of things, though--since you soldered the transistors directly, maybe one of them got fried if you left the iron on too long; bad trace; short somewhere, etc.
It could also be that you just plugged your cables into the wrong jacks. You would still get bypass but no effect.
If you've eliminated the obvious, then it's time to bust out a continuity or audio probe and trace along the schematic.
