Better Late Than Never
Lets start off by saying that I like the soft shading you got going on here. Gives the chameleons a very smooth look. The background remains very consistent with the characters as well. This is also a plus. The scene has good balance and it is a pretty good composition over all.
One thing that dose kind of hurt is the speech balloons. They seem to be low quality and pixilated compared to the rest of the picture. I'm not sure what happened to cause that, but it does kind of throw you off in the high resolution.
Is that?... am I seeing a stock brush? Yes, I think I am. Did you use a stock brush to texture those leaves in the background off to the right? And is that a stock grass brush? Tisk, Tisk, for shame.... But I guess I can't say much, I have been guilty of this myself in the past when I'm in a hurry or just being lazy.
Ah Well, guess its not too big of a deal this time....
Still a decent piece. Nice job, even if it is 3 days late....
