I like it really much, proportions and coloring are wonderful. I think you need to care a little bit more about symmetry, especially in the front plate of her armor (look at where the boobs connect to the lower part, they also bulk in a different way... since the plate is supposed to be stiff, it should not turn with the body, making her boobs accomodate to the armor, not the contrary) and maybe the position of her lifted mask, but that might be possible depending on how it's kept up.
I only see you're character work twice or no more than thrice in Art Center, and yet its still memorable that I can recognized your characters from a game cover. Moment I see those familiar facial features I knew it's Paul Kwon without a doubt! Nice work! Keep up the good stuff!
