I really, really like it!
Good things: The lines are nice and smooth, and the coloring and shading near the hair is good as well.
The eyes should be a different shade of red than the background, although I really love the idea!
Suggestions: I think you should make more details, like whiskers and extra tufts of fur on other places instead of on the outside of the face.
Other than that, it's great! You did a really amazing job on this drawing, and I look forward to the other stuff that you draw on here, and on Hatena!
