Thanks, IHG!
For the basic body structure, all I did was follow a really good tutorial at:
http://www.3dtotal.com/team/Tutorials/benmathis/benmathis_1.asp
It's not modeller specific, but I think the guy used 3dsMAX in that tutorial.
It also helps to be able to modify and polycrunch free models from 3dcafe and other places and attach them to your model.
I know its kind of cheating, but for those really tough parts (hands and head, for instance) it can be a real lifesaver, and can
actually look really good if you know what you're doing.
All teh codez are belong to us!
