For years I've mostly ignored skulls as subject matter, I found the idea of drawing endless pictures of the same thing frightfully dull. Animal skulls, however, are widely diverse but with all the interest (maybe more) of a human skull as a subject. Lots of nooks and cracks, large smooth areas, not to mention that some of them just look completely alien.
My biggest hurdle as an artist has always been completing a 'body of work', I lose interest halfway through and go on to another subject. I'm planning on completing at least 10 skull paintings, not a large number but hey, start small right? Below are the skulls I've done so far...
Saber-toothed Tiger Skull
Burrowing Owl Skull
