I like the stomach.  Very realistic looking.  The breasts are very unique looking.  One of my favorite shapes, in fact.  (Like a girlfriend's from years ago. LOL) The scapula  of the shoulders needs definition.  The shoulder blades in poser figures are notoriously lacking in realism.

The buttocks look more...masculine, than feminine in the back-view.  The spinal trough should be broader at the waist.  Some dimples on either side of the base, might not be a bad idea as details go, maybe.

Fantastic work, so far.  You seem to be on a kick-ass path so far.  Keep on it!
