Inspired by this tweet, I decided to draw Kat as a witch/mage, pretty much all there is to it. I wanted to keep the clothes closer to the original references (ie: long and flowy), but the extreme angle and chunky brush created too much clutter, so I simplified things a bit.
P.S. There's a "crop" version in the attachments, it's basically just a zoom in from her torso up. The other pic is the full-body pose.
