Well, IMHO (and nothing more, really), I don't think that it's any kind of "ugly" factor, but rather the lack of flexibility in the figure.

For instance, Take a peek up there for a moment. I'm able to turn the lanky, scrawny, balloon-tittied, 7' 9" tall tiny-headed supermodel into, well... that. Up there. A short, squat, but still hella-pretty 4' 3" little-thing with real body propotions, that looks nothing like the default V4.

If you can put that same potential for flexibility into the Poser default figures (without undue and excessive work mind you), and still have the result usable with all the common pose/expression/morph sets? Then you'll have something.

It's sorta what I've been harping about all this time, yanno?
