Squirtle scratch sprite

This is actually pretty good for a scratch, Well done! But be careful about those tricky 3/4 views though, and make sure your light source is consistent. The shell doesn't have as much contrast as the body does, making your light source look funky. I would also suggest making the shell's back part larger. The original squirtle's shell was a lot bigger than it's actual body (as far as I know) giving it plenty of room to poke its head out of its shell and get back into its shell without any discomfort, your squirtle's shell here looks skin-tight, and the original's tail was a bit longer too. Just look at some squirtle references and compare your sprite to the squirtle and you'll be good to go!
