On the back side, there are some problems with the soldering. You need to solder all 8 legs of the microprocessor socket. You have 4 with little or no solder and 2 that could use more. Also, some of your solder joints have a 'frosty' appearance indicating that the solder didn't flow properly (a 'cold joint'). Use a clean hot iron and re-flow any joints that are not smooth and shiny. If you are using a low-powered iron (<25 watts) you should pause a bit between joints to let it heat up again.
On the front side, your microcontroller is in backwards. Powering it up this way may have damaged the processor, but fix up the soldering and turn the microcontroller around and test it again. If you can't get it going, we do have replacement microcontrollers
in the store.
Excellent photos by the way
I wish they were all that well lit and focused!
