Keep working at it Rabid Donkey! I've never really been able to nail the 'manga' face so i kind of went my own way.
I have been drawing digitally for so long, I really haven't drawn on paper in forever, except for rough doodles in tiny thumbnails. So I sat down and cranked this one out.
I sketched him in blue pencil, then went over him with a black pencil. I then pressed hard on the outlines and any 3-d objects like the overlapping limbs and the gun. Then I scanned it in, turned it into gray scale to drop the blue lines and adjusted the levels so you could see it better.
There's so much you get with a hand-drawn piece that isn't really possible with a straight digital piece. I've been seeing this happen a lot with my doodles as well. I think I'm going to go back to hand-drawn and just scan in at least the rough drafts.
Or get a thousand dollar 'draw directly on the screen' cintiq...
