I love what you did with the pen tool, could use a little improvement on some of the pieces, but overall great job with it. Overall though, I don't think the design goes with your stock very well, I could see this as more of an artsy stock than a fishy stock. And maybe a bit more color would be nice. I like your bubbles, and you had a pretty good concept with the one pen tool that changes the fish. Would love to see this again just pursued differently.
