These have been done in a figure drawing class and Bob Kato's class at Disney Consumer Products. And yes, they were painted the back of a crescent board~I hate waste..They were about 5-10 minute poses in acrylic. I am still having trouble with my warms and cools so that is why I will be working in black and white for awhile. I am in a large learning curve with both digital techniques and traditional and infact, feel like the girl in Matrix when she plugs into a program to learn to fly helicopters; I come home wiped and overwhelmed almost everyday!
