Nice way to visually pop the dress out. Very good work on the dress too. While I’m not sure I could name the fabric (stiff cotton?) the detail is great and the folds are nice – the top is nice and subtle, the density of creases in the bottom make it a bit harder to pick up.
I think the stomach is not right right now. Fat doesn’t get into that configuration with the top two muscles like that. Or if it does, the vertical cleft should be lost. 
I like how the face reads in the left render in model4m.jpg. It seems a little softer from that angle… but it could be the difference in shader. The dark red wax isn’t kind, and everything else is well shown off from in the 3/4 that you’re using in the most recent shot.
Nice job getting her into position, that pose is solid and natural. Only thing one could ask for is a little more weight on her left hand and then the curve up the spine, but I think that’d be a ton of work to nail down even with the transpose stuff :).
