I think maybe you should add a small line of mid tone to the end of the shade section to make it feel like bounced light. I don't think the lighting on the rocks match with the characters nor do the rays shining through the water.
I really like the no anti-aliased line work.
Her right thumb looks like it's wrong it should be pointed up more slightly.
ahh yeah The other day I noticed that the colors on the rocks/light looked a little..off GOOD GRIEF her thumb looks broken yeah I should definitely fix that lol I should experiment with this gradient shading more and try what you suggested! Thank you so much for your help ;;
Its cool to go overboard at times with art, it usually means you are having fun. I really like this piece, the subtle shading and character design is really nice, i love the cute whale and laugh at the strategically placed hair and sparkles. The background is lovely, I really love those rocks especially. Nice one
