Looking sweet! Love the atmosphere and the lighting (which I suppose do go hand in hand). The fish bothers me for some reason though. I think it might be the flat color it has going on. I think it might work better with some slight color variation, especially on the inside of the mouth and around the gills.
@gforgannon this is looking great. Love it! I think you should add a little bit of contrast in the browns to help differentiate between materials a bit more. @Megacorpse made a good point about it in the "[Hand Painted] Mini Library environment" thread. I also think you should replace the fish's eyeballs with black crosses…
