Erm, maybe we should stop trying to snipe at him. I think he gets the point.
Believe me, after reading all this, I DO.
Everything was very interesting, thank you all for taking the time to respond. I'm sorry if I put you off.
Thinking further, I like yaomon's edit in principle, not just for the shading but for the ball. With my old 32x32 version it looked like he was shooting light/magic/what-have-you at something while facing forward, but that looked a bit strange because he was shooting it off to the side. This makes perfect sense.
Also a great way to deal with these "attacks" is to go out of your way to make a huge improvement on your piece. THAT'LL SHOW THEM!
You're so right, StaticSails!
As for improving my piece, I'll probably make a drawing now (on paper, as I don't have a tablet). I might get to scan it in sometime today, depending on when I find my scanner. It might be hard for me to get the anatomy right, but I'll try. Also I'll probably be using a different pose and intent, perhaps something with the wizard holding his light really high to light something, maybe a cavern or a patch of plains, up.
