Yeah I looked, at least 10 portraits and 2 bigpics are similar or the same. The bigpics look like they were extended to fit the size of the picture, making them distorted. But he got the original art of the guy riding the dinosaur with something to the east I never saw. And a lot of images from the two games I think. I decided that in these cases, since I had hundreds of pieces of art, I shouldn't not make similar art to others. If my art pack was small, or his bigger, I would have paid more attention. That's why I'm not converting any Greyhawk or Forgotten Realms Art; most of it is probably already converted. Some Spelljammer were similar or the same also. I did check to make sure my Oriental Art wasn't used before. Surprising that.
Strangely enough, I didn't notice the Dark Sun hack. I have both computer games, the boxed set and DSM1 Black Flames. Maybe I'll try to convert it some day.
