well...couldn't express it any better, not get me wrong, but maybe you should have a look at teyons work, he's breakin' out of the human-structure-model every day, and the results are more than just perfect (hmm.. I know, there ain't perfect-) modeling. Try something, you're modeling skillz are higher than most of the users in here. Of course, you shouldn't get this wrong, too, but anyway, it's sth. kinda criticism...
