I absolutely love her! I loved the colors you used for the picture; smooth and softly colored. The only thing I can see that can probably need work on is the lines. They look like they could be cleaned up a little bit, generally, I just create another layer and do the actual line-art on top of the sketch. But, some people do like the looks of sketchy lines, so there might be people that you meet in the future that actually like the line work.
But, anyways, I like the character and the colors, and I thought you did a really good job on it! Right on!
