I went back and colored my earlier drawing of her. My friend's preference for black made it harder, but I got some practice. Here is the uncolored version in case you'd like to see the design without color; https://www.furaffinity.net/view/16897159/

Mentioned in the uncolored version, this armor mixes elements from Mass Effect and Halo 4 and some other random scifi stuff. The blade has vibrating cutting action and is microfactured and disposable so it can be broken off inside the target and replaced.
