I think you should really push this alot more Kurt.

As Im looking at and Im seeing just a model that could have been done in Maya alone right now. Push the detail to an extreme. Then if its too much dial it back by dropping a resolution or two.

I feel the creases around the bra/breast area would be non-existant because the breasts would basically fill that area out, unless shes got a set of saggy hot water bottles under there. Check some references

the model seems caught in the world of a Pixar animation and something off Captain scarlet, and would I think benefit from having some more detail put into it.

cheers
