couple of things:  i like the pointy breasts.  some women have more conical shaped breasts than apple shaped ones.  i think the join of buttocks to back could be more accurate - right now they kind of look as if there's a slightly odd roll of flesh at the top of each one  that i don't think i've ever seen even in unfit women. 

i like the shape of the eye a great deal.  on the eye geometry itself i'd say recess the iris. everyone's going on about how v4 looks more like a doll or more toony or whatever.  i think most of that is because people focus on the head, and because her eyes are very unrealistic, imho.  i've seen lots of different textures and read a tutorial, and all of them looked almost unacceptable (again, imho).  one reason is the shape of the her eyes, a hurdle i think you've already jumped.  but the other is the depth to her iris.  as bast black said over at daz, she looks like she's wearing contacts.  depth isn't acheived just with highlights and reflections- it's created with shadows.  all the modern eyes i have (awful eyes, millenium figure's eyes, and the light version black eyes that came with irina 2.0) have recessed irises.  v4 has a confusing number of layers to her eye, but the best textures still look more dead to me  than i can get v3's to look with just flat colors and the right material settings.
