Sometimes a sketch just speaks to you. I was doodling the one on the left while in the waiting room at the eye doctor, looking forward to a battery of tests that would probably kill any productiveness for the day. After dinner I was looking at the sketch and immediately saw the Scarlet Witch in the face. I redrew it on the same page and made it Wanda. TaDa!
I think the first face looks better, but thats the way it goes. This was all done with color pencils in my sketchbook. About an hour total time.
