I like your solution, I never even thought of a fish when the word "slither" came up. I think it could benefit from a little bit of splatter and slime though. Dizzle.
This is beautifully done. Yes, please do more!
Very nice. Composition, colors, the idea, and I especially like the hands.
Nice. The ring finger on the "open" hand bothers me a bit, but I like the overall feel of the piece. It's a good color study as well, so to speak. I wish the background pattern was bolder, but that might just be me : )Thanks to you and Jon for doing Illustration Friday. It's a little addictive. I hope the next word will be as fun.
