Sorry, I'd have to agree - I prefer Tycoonins pics. Yours lacks definition and is a bit too busy for me whereas his, although monochrome, is sharp. When you fill the canvas with colour, it masks a lot of mistakes. With Tycoonins black-on-white, every little mistake shows so he's gotta be on point the whole way. Just the eyes of Al Pacino (althought i thought it looked like George Harrison first!) are excellent.
EJD - post a few more pics, blow them up a bit so we can see them more clearly and include one or two monochrome ones (if you have any). One example is not enough to make any conclusions.
