~New to CA~ Tear me apart

[Iscariotx]

Hello, Hello. I'm new to CA, obviously, and I'm really hoping for some feedback. I plan on starting an art career once I graduate from high school and I have A LOT I need to improve on before getting there. That being said, what do you think?
Sorry, I can't afford a scanner right now, so digital pics will have to do.

cool stylization, I have a friend who does portraits in a similar style. This is a hard work to criticize because of said stylization, however. I think right now, the only thing that needs some fleshing out is the values. There is no real dark gray tone, it goes from black to midtone without any in between. This is especially noticeable around the nose and mouth area. Also, you might want to try varying the thickness of your outlines in future works too, it would probably make it more dynamic. Good start, keep it up!
