Nice drawings... you definitely have talent. Keep it up!
The self portrait is actually pretty good, man.
I suck at faces. Faces are always hard for me to draw. I give you respect.
You should try water colors once. I think you might love it.
Oh I have done some watercolors, in art class, and most of them were pretty good. I enjoyed blending, so i did a lot of stuff like sunrises or sets. I did a cottage scene one time with trees and stuff around it, i liked doin' trees too, turned out pretty good. Need to try to find some when I'm back home.
