It's her boomstick :)

I've made some corrections, and added a little blood on the chainsaw. Thin I can call it over now, time to made another one !

Nice. Good char concept; name. Left side white line of right shoe too bright. That a baseball bat or tuft of hair rising from her back?

Great stuff. I like the subject matter. Good colours.

 with less cloths it would be more awesome 

The chainsaw doesn't looks, uh, very dangerous... It lacks of, uh, sawtooth ? (not sure you say that in english, sorry)
It's alot less obvious on the blood version, tho;

Anyway - the posture is awesome, its brings lots of life into the character. :)

 animate the saw for epic sauce dipped in bacon

Nice one, I liked it
