This is something I always wanted to do, but never had the time to until now: a study of a dragon's head. It's a first, so please remember that when you look at it.
I'm part of the Ultima Dragons, a fan club for Richard Garriot's Ultima CRPG series. On ye olde internet MUD, each of the members was able to transform into a dragon. This is what I visualized dragon form as, minus the color. I'm a gold dragon, of course!
