This is Sistine, my account mascot.
She's a raven with light grey Flight Feathers, a scarf, goggles, and a pocket watch.
Sistine is fantastic with machines. She loves to build, reconstruct, and modify them to her liking. Sistine does have an evil feel to her. She has an odd way of talking, and is cold with people. (Well, animals really.) There is a legend that her pocket watch has some mysterious power, which she enforces.
Sistine lives in a clock tower, and takes care of it as her day job. In her spare time she tinkers with machines, or works on client assigned work.
This was drawn in CS5 on a Wacom Intous 4 large.
Time: A few hours.
