This is one of my grad class exercises for the first week. I had to render three different lighting source for Captain America. Now the funny thing is, I have been painting in Photoshop for years and had never experiment painting in such a way; applying colors that doesn't contain a single black value within. So this exercise was really insightful for me and maybe, it might be my new way of doing digital painting.
