I sent the guy a note, but judging by his ID, he may be trolling. In which case, he may not comply at all. I'll report him too if so. Judging by the popularity of most of the works he's uploaded, he may get his account deleted/suspended before long.
At any rate, thanks for letting me know, and thanks for reporting him.
I shall adore your works forever and a day, specially your dragon pieces! probably my fav part about this piece is the lighting on the water.. and how realistic this looks. I could easily see this on the page of a dragon encyclopedic book!
