That yellow on the front of the face says so much! Then you added that pale blue for other contrasting highlights, geezal. Someone got an 'A+' in color theory!
The closest I got to doing colour theory was painting a colour wheel. I'm really interested in colour though, I must find some good books or articles on colour theory.
Woah, all natural! I have a few color theory books back in the states i meant to bring them over. Ill have mom send em, haha
