I'm with setz on the countours of the lines. Otherwise good stuff.

Thanks for the comments.
@ Setzer, that's basically the way I did it, but without adding layers, (on Paint) I was lazy. Might fix them later, though.

I think I might've liked it abit better iff the black lines would follow the frog's body, instead they seem to be drawn as a transparant overlay. if that makes any sense

Yeah, you finished it, and what a job you did
