Not bad, I think the dress should of been done abit better to show the folds in it, but if the drawing itself showed no sign of folds, its admitedly hard to make them with color only.
Very well done with the eyes, I find drawing them hard, but have yet tryed to even color them in black and white, as I can very get the light right, when drawing you need to think about where the lights comeing from, this one shows no real sign the lights comeing from anywhere, alltho the eyes have "glints" in them, giveing it feel there is light there, shes is not just standing in an empty void.
Love the hair, the shadeing on it is near-perfect, when i draw I only use 2 colors, a base color and a darker verson of it to show the shaddows, I think its very hard to put in 3, a base color, dark color, and a light of just white color, since its annoying figering out where to put it, and most people go over the top and end up ruining it, this one on the other hand is fine, wel done.
I cant think of anything else... how she gonna play that with no strings anyways?
