First, I'd like to say thanks for taking the time to make a model and then offer your work for free. Thank you.

The model loads fine in Poser4 on my Macintosh. But there are problems.

Shoulders, forearms, and hands have the "Bend" and "Twist" reversed. In other words, bending the body part twists it and twisting the part bends it.

If you rotate the collar forward, it seperates from the torso. If you bend the chest, it seperates from the abdomen. And when you bend the abdomen, it seperates from the hip.

Some final thoughts. If the head has no moveable eyes or mouth, then there can be no expression. But much can be expressed with the hands if only the fingers were posable. The image of R2D2 came to mind. I mean, what could the director of Star Wars DO with it to make it expressive, other than shake it from side-to-side and go "Bleep! Bleep!"?

Just some feedback. Hope it's constructive.
