Interesting. Did you start with covering the entire area in charcoal and erasing to get the desired shade? Most people seem to think it's harder to do it that way, but I prefer it.
I haven't worked with charcoal for so long! You're making me want to get some heavy duty paper and go to town >.<
As soon as I finish it I can get whoever prints. It just cost shipping and idk what id charge not very much though! Just shoot me an Email with your info!
