C+C request, sprite sheet of my persona.

The hair needs more contrast, don't use that nearly white blue, the shading is barely visible. Besides it looks really blocky, you might want to rounden the top more. Also, your lines need a lot of work, they are really jaggy, as if you just doodled them. One does not draw sprites, one pixels them.
I wont even start on anatomy. You really should use some references on how human bodies look. Of course that's hard for beginners. I haven't quite figured it out myself
