Messin' with Characters

So Its been a long, LONG time since i posted anything (I've been really, REALLY busy at the office).  but I've managed to find some time over the last few weeks, and i decided to start a character of some kind.  Right now, I'm leaning toward a female mech-type character. I've started with a base sculpt of a woman to build off of. Areas below the elbow on the arm, the hair, and below the ankles on the legs are still in blockout form.

What do you character guys and gals think?  Not bad for an Environment artist? Ideas, paint-overs, feedback, anything, always welcome.  :)
