Yeah.. i somewhat thought so too... although i draw that one beacuase i really like the pose... it shows his personallity in a good way.. you can see his body well... and he looks like he doesnt like taking pictures .
Um, nah...I think he drew it. Open the fanart in one window and minimize it, then place it next to the wallpaper on this page. Notice the large amount of differences? It's not the exact picture. I think Lex is right, it's a redraw.
