At first, I was wondering why this was so high rated. It just seemed a picture of the red knight at first. You should call him knight and not dude. Maybe you're a fan of "The Big Lebowski". I love how you see the electricity coming out of his hand. The shading is wonderful too.
You really get the feeling that he's looking at you. It's great perspective. Even with a helmet, he shows great expression. Or is that really his face? The background's great too.
