Too much dithering. Try to avoid dithering skin, especially smooth skin. Also, the shape of the head, the perspective, and the placement of the eyes all kinda seem to contradict one another.
Also, what's with the ears?
If you were going for a totally realistic piece, then there are definitely flaws. However, it kind of transcends them and becomes good in it's own way. I like it.
i wonder if this strange thing between hairs and left eye is an ear? now it looks like a tatoo or something like this (;
Way too much dithering. She looks like a vampire from twilight when they stand in the light. Ew
just as Pumpkinbot said, that dithering is way too much... buut... who said its a bad thing??? :P it gave it a retro feeling... really good 5/5!
