All right, as much as I hate asking for help on this kind of thing (I'm all ready self-conscious about my art) I need to ask those of you who are way better at sketching and line art for some help.

I am hoping to learn how to draw Nathan Explosion, the issue is, I can't find any kind of full body example I can use. I don't want to trace him, I want to actually teach myself how to draw his body structure and features in different ways and styles.

So I implore you, if any of you have some kind of Tutorial on basic Male structure that fits his size/type, Advice or if you have anything at all that might be able to help with this, I'd greatly appreciate it.
I've tried using a mannequin and a few other Drawing books, but nothing has been coming from it.
