I just came across this guy's site!
It's run by artist D. Alexander Gregory. Go check out some of his stuff; it's brilliant. Try image-Googling his name as well; there's a tonne of fantastic bits of art with his name on them, especially at the Wizards of the Coast site.
I particularly like his dragons; they're a little more "feral-looking" than the Lockwood AD&D standard.
I now have a new goal: to sell enough of my books that I can afford to have this guy do the covers, if only so that I can put "Written by D. Alexander Neill; cover art by D. Alexander Gregory" on the frontispiece.
