This is a real fun style for you! I like it a lot! might've chosen a darker outline color (dark purple works well for me, though dark brown might've worked better here)....
I'm kind of mixed on the color issue. On one hand, I think the cat's colors are really well-chosen. I also like how you did the tuft of fur at the end (both colorwise and shapewise).
On the other hand, I think the yellow of her shirt-thing blends too much into her sock and belly color--maybe that's what's tripping you a bit.
I really like the near paw. :) Nice details.
Ha! First comment for me! At any rate... I like the colors, the pose, and the purple bandana thing on its head. Very nice!
