The lines are very good. You should tone down the staturation just a tad. I can't really see the shading too much but you might have wondered off into pillow shading in a few areas like the hair. It also doesn't hurt to shade in the lines either.
I really like the character design here. You might want to work on the hair a little bit though, the shading is really easy to see, and I don't know, I just don't like that.
Finally i see a hk with a interesting design. Colours are good, could use more purple in darker shades of blue dress. Also remember clothing leaves shadows on your skin, so shade them in on the template. Increase the contrast slightly on the blue and hair.
