I thought this would be more about a fish that was evolving. That is, I would think the title would be about that. Apart from that, it's still a pretty good picture. What really makes it work is the sort of grainy effects you put into the background. I know realize it is more surreal as it also has front hands or arms or whatever. I like how the bubbles are different sizes, too.
It also makes you realize that this fish has no front fins, or middle fins or whatever. Anyway, it's interesting to see the creepy tone the fish has on his face. The scales are pretty nice too. While not well detailed, it works well for what it's supposed to have. Not much else to say, except nice gills.
