Looking pretty damn sweet!
I like the pose.... The modeling is good overall, but the feet seem kinda weird! Maybe they're too small?
Also the thickness of the Chest through to the back, seems off, as well as the general shape of the back.
The head looks good, for a Anime-ish style character.
oh, and she needs eye balls.
The scene itself looks really good. I like the city scape in the background.
"Your weapons are no match for ours! People of Mars, surrender!"
"Um, this isn't Mars. This is Earth."
"Earth? Earth-with-nuclear-weapons Earth?"
[long pause] "Friend!!"
