Here is the reference sheet I created for Nax to go along with the sculpture. The winner of the auction will get ownership of this character along with the sculpture. I apologize for the watermark. Since the full reference sheet will be sent to the winner of the auction, I didn't think it was fair to post the unwatermarked version online.

Done in Sketchbook Pro for iPad.
