picked up "an atlas of animal anatomy for artists" this morning... i think it's awesome how every animal skull appears to be smiling, yet with all their skin and hair animals very rarely appear to be smiling. my dog jack looks like he's smiling every once in a while but really his lip is just stuck to his teeth... he has a dry sense of humor anyway.
*oh, and the drawing was done with a pentel brush tip pen... it takes some getting use to but you can use a damp brush over top to get that washy look.
