I'm not a big fan of using the netting, but I need to get over that. Finding just the right enough contrast is tough. I do like how it breaks up the "dots" down the side, though. I have started thinning epoxy with alcohol. It helps quite a bit, but I thin it more than you do. I also put the baits on a wheel to keep the epoxy from sagging. Anyway, nice work.
For photos, I bought a small table-top product studio kit. It was like $35 on eBay. Came with lights, and a white box that diffuses the light. Your orange spotted sunfish encouraged me to give it a try. This is the first run at it. It was photographed in my little $35 studio.
