Street Soldier With Wings

This is supposed to be the soldier from the cover of Linkin Park's Hybrid Theory, by Mike Shinoda.
A project for school where we had to pick an artwork to copy as to improve our painting techniques. As I don't have many to start off with I decided to stick to the seemingly simple. Trying to use techniques to imitate spraypaint.

None of this is traced, I copied it by hand. It would've been better if I had decided not to brownwash it T_T. This has been scanned and minorly touched up with photoshop. Not much as I don't even know how to use the program, and uh I don't know how I did whatever I did. I accidentally scanned it greyscale, so I added colour? Somehow... CK
