Collywobbles: Thanks for the kick in the pants!
and to add a bit to what Collwobble was saying. Always try to keep in mind the measurements of the body. Like for example, the face proportions can be divided up so that the placement of the eyes, nose, lips, etc can be placed more accurately. Read Loomis' Drawing The Head and Hands page 23. Also, the body is symmetrical. So if your looking at an ortho front or back view. The left side of the body is going to be the same as the right side. This is true even when perspective and movement is involved, it just becomes a bit trickier.
I wanted to share this sheet with you guys. I made it so that I could print off a bunch of them and just study the hell out of 'em. Hope they can help some of you.
Made it a little extra big so you can print it off if you want.
and a little example of how I'm going to use it.
