Painting Competition - reposted

Oops - somehow I managed to delete this post! Guess I'll re-post. Sorry to those who commented and got erased!
Anyway, this is for a painting competition I'm participating in. The task is to pick a master's self portrait and do a caricatured study of it, being as accurate as possible to value, colour, and even painting technique. Naturally, I picked Sargent. It took me about 8 sketches to get to this point, which is a full value study. After this, I'll begin the final oil painting, in colour. Below my painting is Sargent's original self portrait. He's the man!
