i think changing the color of the highlight on the hair would be a good idea. With red background and a very close to white skin tone, the white hair highlight at the first glance creates an illusion like the character is balding :D

That, and the face feels kinda flat, my guess, because the lips are disproportionate to the face and break perspective a little. But i can see how if i tried to draw it myself, concerning over curvatures, perspective and whatnot, wouldn't finish even the most basic of sketches even in an hour. So yeah, i'd say you did quite good. Despite the rough strokes, the work creates a feel of gentleness that i can't quite express, but pretty-much makes the artwork a pleasure to look at.
