Imy, I guess

My first thought about this drawing was how pretty the colors were. And how cute she was.

Good Things
- The Anatomy, you're really good with the body, and she looks so good. Everything seems to fit together, and I can not see any huge mistakes on the anatomy.
- The coloring is really nice, it suits your style, and makes the drawing look a bit rough but at the same time detailed and nice.
- Shadings are really good, and you've managed the shading well in this drawing.
- The colors matches, and is really well put together.

Things that could be done better
- Her legs are very thin, and her ankle is standing in a strange direction. It would hurt a lot to do that in real life.
- Her hand are a little too small, and I think they would look better if they were a little bigger.
- No background. Not really a bad thing to not have. But most drawings look better with a nice background <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)" />

All in all, a very nice drawing. You have amazing skills, and I'm sure you will improve even more. Hope my critique was fair, and that it was helpful for you.
