Did you know that the word modeling has only one "L" in it? For some reason I always chuckle when I write that. (as opposed to "sepArate" vs. "sepErate", which my brain seems incapable of ever remembering).
Anyways, more to the point, here are a few videos about MODELING (heh heh) that go over some basic stuff that pertains to animation. Did these quite a while ago and forgot to put the Vimeo links here on the blog. Oops.
These go over creating and using edge loops to get the forms you want while keeping the poly count low, localizing additional geometry you're creating using loops, and some general tips about modeling for rigging. The general idea of all of these is to point out that modeling for animation and production has some different requirements/goals than animating for, say, stills or for turntables. Some of the stuff is pretty basic, but things that I see done a bit wonkily fairly often, so there you go . . .
