That is really good. Just one point of advice...you should increase your aperature slightly so the grey rock in all in focus. That is the only thing I would change.
Thanks...even though I shoot digital, I still don't check my shots before I get home, because for some reason I think that that's dumb. I shot this at f/1.4 just to see what it would turn out like and got a little too narrow a DOF...and I added contrast in my RAW converter, which makes it seem a little fake.
