In keeping with my effort to stay loose and lively, here's another whimsical skull in brush pen. Isn't he fashionable on plaid? I pulled out a gray prismacolor marker to help push the pattern back a little. This would have taken me a few extra hours if I'd done it with a technical pen, but I'm thinking once I get the hang of this brush stuff it'll be great to blend the tools together... using brush for the fat and flowing outlines and pen for fine detail and hatching. Lot's to play with there!
On a side note, as a metal fan I'm well aware of how cliche skull art is... yet that allure is always there! Must be some kind of primal fascination in us.
