Hey, this is pretty decent. I've always been hopelessly attracted to messy hairstyles and strong eyes.
Not perfect, though. Her arms are the first thing that jump out to me: her left arm is longer than the right, and both forearms (I believe this is what the previous reviewer meant) are thick compared to a slim body. Also, a human's wrists align about with their crotch; on this girl, they're just below her navel. This can be remedied by making her forearms longer. Last thing for that area, try making her fingers align a bit better. They separate from her palm as random places; they should be going in a slight arch, with the pinky being the lowest and the index finger being the highest.
Her legs looked really nice to me at first (and the front one still does), but even considering foreshortening, her back leg is really small. Correct me if I'm wrong, but I'm assuming you did that because you knew that there was a gap between the legs just below the crotch and wanted to accommodate that? True, there is a gap, but it's often too tight to even fit a finger through. That sounds pervy, but think about it artistically.
Going back up her body, her sleeves look too two-dimensional. The way the white rings are curved, we should probably be seeing a little bit of the insides.
The coloring and shading are pretty nice. If there are flaws with either, I'm not skilled enough to point them out.
