This nifty painting comes from Harek of Ingebrigtsen, Spain. "Hey! Recently I've been fiddling a bit with watercolors, and find bones to be very gratifying "models". This is an early skull, painted this in 2008 on a night watch."
I really dig the simpleness of the two tone design you created. It gives your "model" a great primitive look like something out of an old horror novel published long ago. Possibly an illustration for "The Screaming Skull" by F. Marion Crawford. Thanks for bringing us a basic lesson in spookiness.
