Oh, thanks. Yeah, I think you're right -- I didn't do a global adjustment of the shading on this one, and it must show. I usually go back over a drawing and match tones across the drawing, but this time I was a little worried about screwing up the fur, so I didn't do it.
I'm also not happy with the mouth, so I may go back and work some more on it. Thanks for the concrit, it's really helpful!
