Showing you the sketch for approval before I draw anything, let me know if you want me to add or change anything. Scar on forehead (I'm a short person so I usually ran into things head first I don't how how it would differ for an average or over-average person but to me it makes sense for him to be running and then smacked in the face with a tree branch) I also added bags. Oh and I gave him like a camo shirt that's supposed to have cloud patterns on it. I added the black around his eyes because that helps blocks the suns rays from hurting your eyes. Oh and for the pose I made it so that he is trying to look smaller (trauma response), maybe I will also tilt his head back a little to emphasize it more.
