The model is crude and badly proportioned.  It isn't even as good as the ancient Poser 1 figures were.  I suggest you go back to "square one" and learn modeling, then study anatomy, then study existing figures such as V4 and M4 to see how they're put together.  

If your goal is to create a commercially viable product, you have a LONG way to go.  And you should be aware that Poser users are used to figures of FAR higher quality than this.
