SUP DUDES. I just wanted to share this site with you all - a Russian gentleman who goes by the handle "Amok" did a bunch of ASOIAF art, and I like it quite a bit. It really shaped the way I saw - and continue see - the characters. Particularly Syrio Forel. I can't stand that he's not bald on the show. :|
Michael Komarck does some great stuff too. This is probably my favorite ASOIAF-based picture OF ALL TIME.
ETA: Some of the pics in Amok's gallery are a tad bit spoilery! Nothing too bad, though, probably just a bunch of characters you've never heard of.
