Prince Valiant light study

My buddy [link] gave me a book by San Julian, a spanish artist that I never heard of. Well, needless to say, I like this guy's art style. there's a picture in the book in which he's working on a painting, and what he's doing is painting the figures first, then the background second, which is totally against everything that I ever learned. So I did this drawing, based on the San Julian book cover, in order to make a color study later.
