Future Donatello in charcoal

Here is something kind of unusual. A fan wanted a Future Donatello (diff mask used a couple of times in the Mirage and Archie books) drawn in a different media than I usually do my commissions in...hmmmmn.   So I decided on charcoal on green paper. I use charcoal for life drawing but not really for much else so this was a cool chance to do something outside my norm.
