Your best bet may be to ask the artist on another site if they're on Weasyl. You can also look through my list of people I'm following. On that there's quite a few very popular artists that you may know. ^^ You can also just use the search option, although that, for me, hasn't worked too well for some artists. ( A few have come over here with a new username, like wolf-nymph for instance)

I know that Windfalcon is on here and useing that name but the only search function I have found on this site does not find anything!
