Alright, I went with a high contrast sort of thing to make it easier (and cheaper) to print. I'll mull it over and fix anything that jumps out to me (or you!) to change and then post a customink.com link where people that want it can just go buy it. I don't see any money from that, but it's not like I'm a pro or anything. It's all vector, so easily editable. The hand bugs me...that'll probably change.
I rather like the idea of having a Che-type shirt with Warren on it though.

Fantastic. Perhaps a way to improve the hand (and the overall composition) is to give the hand, especially where the fingers overlap, more shading, like you have on the face. That'll give it more definition and will balance the picture as well.
I was thinking about that. I also realized that part of the reason the hand looks weird is that I actually fucked up the hand's angle. I got some sketchy outlines from the picture, then added the darker details myself, and somewhere in between the angle changed.
I'll fix it and post a final one in a couple days with the Custom Ink link.
