Mechanic and Valhalla girl

Hey guys, I've been cooking up a bit of back story for the mechanic. I even gave her a real name!  First Sargent Charlotte (Charlie) Jackson.  Aka Gears/Sarge/Boss or Queen bitch of the grease monkeys.  She spent some time in the trenches before the higher ups finally figured out she was a talented machinist, and moved her to the armored fleet.  Since she's so short, while in infantry, she got stuck as a tunnel rat, and would be sent into mines and tunnels that got dug under opposing trench lines.

Also some doodles of Sasha (Valhalla Girl).

Cheers.
