I didn't say the angle of the shadow was the problem. I didn't really say what I thought was wrong with it, my bad. It's that it looks like it was painted in. It looks to "perfect" like he took the picture of his head then filled it in black, then made it a transparency. The edge just looks to sharp for me to think it's a real shadow.
I've looked at his other pics and I'm still not convinced. Maybe I'm wrong which would be awesome but it just looks fake to me. But I will say that the halberd does look real.
