Sorry if she's a bit dark, I wanted to try to get her to be like a dark green-black color, but nothing was really working out. :P So this is the result. I can always lighten her up a bit, if anyone wants.
Here's Admiral Osman. She was only really seen once in Halo 4 (Spartan Ops #9). It's not always easy to draw a character that a) only shows up once and b) isn't even completely shown (she was sitting at her desk). So I had to improvise a bit. :)
