I like his face, and the texture in his fluff is really nice.

Your paperwhite that you've scanned could look a little cleaner, however. There's a tutorial here: http://www.furnation.com/chipmunk/articles/cleaning/section0.htm on how to do that. (The next page actually shows you what the tool looks like, so you can use it even if you don't have a fancy art program).

Anyway, making the white background cleaner is going to make the picture look more professional when displayed on the web.

Its very cute, I like the coloring/ lighting. :)
