Brain melt - Cassian

I am seriously stuck. I decided alternating pieces that I was working on and I pulled out an incomplete from 5 months ago. I don't know what I'm doing with this. I got it cleaned up some and darkened much of it. The face was given me the most trouble. I've re-drawn in many times, and it's always felt off. I cannot presently tell why. Blargh! (edit: added further progress at top).

This is the original drawing idea. It started as a pretty simple pose with practically no armor.

And this is where I left off. It felt too washed out, and so I went in and darkened stuff up and redrew the face. It was too grey.
