Love this piece. It's the casual atmosphere that gets to me. Most fantasy pieces show characters slaying dragons or fending off hordes of enemies or somesuch. You don't see many that show them just chilling. The colors you use give off a dull (dulled?) impression which isn't quite to my taste but as stated - that's my taste and shouldn't be taken as objective criticism or any criticism for that matter.
... Aaaand they're still actively trying to kill eachother. Gotta love the Drow.
P.S. I saw the mind-flayer testing his drink for poison and lost it right then and there.
