I'm an EscherGirls lurker, and for those of you who have been living under internet rocks, EscherGirls is a site that posts and analyzes comic characters (particularly female characters) being drawn in obscene, rubber-spined ways in order to showcase as much boobahs and ba-donka-donks as possible. The whole T&A thing is not new to comics and it probably won't be stopping unless 1) comic artists realize that women can be sexy without presenting like baboons in estrus and 2) comic artists actually learn that comic characters (particularly female characters) have these things called bones, organs, and spines that must at least somewhat adhere to the laws of gravity and physics.
That is what SenshiStock does. It showcases typical poses that you'd find in any given comic or graphic novel, such as sitting down, punching, attacking, jumping... All stuff that is good reference material for the aspiring (or perspiring, whichever you are) artist who needs to get a grip on how anatomy, perspective, and gravity/physics work.
Have fun, and happy drawing! I'll be utilizing a lot of that page meself!
