Superman is the hardest character to draw. There are a couple of things that make him difficult. He's got a very simple costume and doesn't have the long cape like Batman. He's not a character that is necessarily always in shadow, and he doesn't have a mask.

The way you challenge Superman is by having things happen very, very quickly in different places and then asking, 'Who does he save first? What powers must he use to save each person or stop each disaster?' That's one of the ways you make him interesting beyond the thematic and moral issues that make Superman.
