Sorry I've been slow to update. My class with Sam Nielson is about to come to a close, so I will be posting a bit more regularly very soon. In the meantime, here's one of my assignments, painting hair. The original monster design is Sam's. The rendering was left to us. The feathers in the mouth were my idea. :-)
If you're really serious about getting better and learning everything you didn't learn in art school, but should've, I'd highly recommend this class. Just realize it's a humbling experience, but one that will leave you all the greater of an artist for it.
