You do this daily? This is great!
I like the blue coloring you used (when I first saw it, I mistook it for a slime girl or a ghost). The shading on the skin of her face is what I'm most impressed with. It baffles me how artists can have such a great understanding of how lighting would affect the objects in the picture if they were real. The nose, mouth, and hair are all great, but the eyes may be a little too big if you were going for a realistic approach. However, the big eyes do make her look attractive.
