I'm not a pro, but here's my big beefs: Straight, fully symmetrical poses. Almost no one stands or sits that way, even with good posture. Hips angle one way or the other. Shoulders drop. Feet angle outward at differing amounts. Eyes looking right at the camera. Most of the time, it looks artificial. Eyes that don't crinkle. When you smile, your cheeks move up and that forces your lower eyelids up just a tad. If the smile is wider on one side, then the lower eyelid on that side moves up farther. (Vicki's Wince or Wince 2 works wonders.) The adjustment is minor, but it can really make a big difference between a believeable smile and a plastic one. (Remember the cliche: the smile didn't make it to the eyes?) Static eyelids. When you look down, your upper eyelids go down. Looking up opens the eyelids up. The brows will also affect the eyelids. Ignoring gravity. Just try standing in some of those poses and you'll see what I mean. If you're interested, I have 2 tutorials on these issues at my site: http://www.fallencity.net/lore
