Firstly i like the model and the gun. They both look really good, although I thiink looking into some anime characters would be extremely helpful.
You have said that you want her to be strong but there must be a better way of going about it. My suggestion would be to reduce the muscles still showing that shes strong but not to the extent of the present model.
The gun looks great and quite detailed without going too far.

Thats my two sent........tences. Actually more than that.
Great models and hope to see what you make with it.

Go to this website and download the trailer of the animation Appleseed it might give you a few more ideas.
