I'll start by saying I like the body, those are some interesting color channels to play with. I also really like the back of the helmet, the energy effects are neat, and the "ears" on the side. The front of the helmet is what throws me a bit.

I feel like if it wasn't for the... ridge? Up on top of her forehead and the shape flowed smoothly it would work with the fairly simplistic face plate and look fairly elegant. I also feel like the current shape could work with a bit more going on to draw your gaze in the face plate, so there's more than 1 route to improvement here in my opinion.
