Thanks Sethski.
I guess the Gulliver's illustrations are some of my favorites.
In terms of the different body types and poses, I try really hard trying the ones that work best for the subject matter. In addtion millions of hours watching naked people really helped. (Seriously, logged in millions of hours doing Figure Drawing back in college, saw more nude models, than a regular at an adult entertainment bar.... :))
Knowing what I do, and what I wanted to learn... I spent not only a lot of times getting the human figure right, but learning anatomy as well, cuz when you do cartooning or animation, the only way to properly do it is if you know what the source material was exaggerated from....
As far as SIGs go.... this could be something I'd consider... especially since it deals with Star Wars themes. :)
