Holy Crap. That's all I got to say. No, actually I got a little more.
Very impressive work! I particularly liked the shot of the girl in that "power suit" or whatever it was, the one wearing glasses, where she's just sort of sitting back. Incredible attention to detail, and interesting to see somebody dressed for battle but just kinda chillin'. Not to mention, it's refreshing to see a girl depicted wearing something that isn't skintight, low cut, and horribly impractical for fighting.
I wish like hell I could afford an artist like you for my project, but I'm stuck posting in the "Non-Paying Jobs" section as I look for an illustrator. Oh well, best of luck to you. With your sort of talent, I'm sure you'll go far.
