I might as well post my entry now as well, since I'll probably forget to do it while at work tomorrow.
This was done with MSPaint using a mouse. It took a bit of time this weekend, but I've been having a lot of fun doodling around with MSPaint recently, and this was a nice way to take a break from work. And well, I just love Mummies.
Thanks Daniel for the really fun contest idea.
