I used to do pictures and enviro. I frankly just got tired of the process. It's almost another week just for finsihing. Been doing this for a good 12 years now. I just can't be bothered. Post paint pens work great.
Your solder could make do with a reflow. Some of the pads look like they have no solder at all. I’m sure they do, though. The solder should flow through the hole. Also, check all the values to insure nothing is off there.
