What happened to U3U? I think I can see bare PCB material there...

some tips: look for the macro setting on your camera, if it has one. also, back off on the distance and let the camera actually get a proper focus confirm. if you are too close, the lens simply won't focus. backing off will give a better focal length and its much more important to have focus than to 'fill the frame'.
avoid flash and use the self timer. set the self timer, turn to higher ISO on the camera and hold it still (if you have no tripod).
as for soldering, I think all connections on the chips (at least) need to be reflowed. they are so uneven I would not trust them. you should get paste flux, run a line down the side of the pins and with the slightest amount of solder on the iron tip, 'brush' or 'paint' from the chip plastic toward the end of the pin. with lots of flux (jelly paste stuff) and a clean tip, you should be able to get even, regular looking joints. what you have now is simply untrustable, entirely. that goes for the small voltage reg chips, as well (those are hard to solder for most people).
after you retouch all critical areas, you need to truly clean the board. buy the stuff in the can ($15 a can or so) and use it! use a tooth brush (new one, lol) and brush that off after some canned anti-flux.
if you did all THAT, then there is a chance you could fix it (just by that) or at least people can give you meaningful advice over the net.
1) quality of soldering, use of lots of flux, no skipped steps in board cleaning
2) quality of photos matters
