Well, the artist actually started posting his material on FurAffinity recently, and from his journal it looks like his car has died, so he's selling off the originals of a lot of his art. I didn't see anything outwardly as far as either an auction or an asking price, but not only did he post the works, he's offering to sell them if you're interested.
