Very Rough Doodle

I've posted a few finished pieces in a row so it's time to slouch down the stairs and answer the blog's door bell in my boxer shorts and old Grateful Dead t-shirt.

Here is an informal doodle. While trying out a batch of wild and weird Photoshop brushes I rediscovered on my palette, this very grubby thing happened.

Maybe 10 to 15 minutes total drawing time, with another 20 minutes wasted fiddling with the controls on the brushes.
