Sparky or Steffi

i wanted to draw a spunky mechanic. she is able to change her hair color at will, though she is unable to change anything else about her ('cept how she acts, of course). Her real name is Stefanie, though most call her Steffi or Sparky. she is brilliant, but extremely shy and secretive. she is also extremely adept at fighting. her favorite weapon is her wrench or her crowbar.
hight: 5ft7"
weight: she'll never let u find out (90lb)

she is (c) to me. that means no stealing, tracing, copying, etc.

Anyways, enjoy!!!
