Very cool pic, and an original idea to make his head look like a moon! :D
I would suggest a bit more shading, and the colouring on Santa himself looks a bit rushed - try and make your colouring more solid with no white gaps. ^^ But I like this picture a lot! :D
You seem to be making a lot of threads for single drawings - I think it might be better to just have one thread for all your art since they clutter up the forum a bit. :)
