I like Superman, he's the original and greatest of all Superheroes. I read a lot of classic Superman when I was a kid. I'm not sure that I have ever managed to draw him to my satisfaction though. He shouldn't be too ripped, but he should be massive ( like Curt Swan used to draw him ), he should never look like he's straining that much either. Too many artists draw him looking like his toenails are being pulled out with pliers. There's a magnificent grace to Superman because a truly great Superman story is rarely about physical duress, it's about morality and ideas. It's not about extreme violence ( unless absolutely necessary ), it's about finding out what right and then doing it.
