Funny, I was reading an article in the Doctor's office (Outdoor Photography, I think), and it's focus was how to use Ansel Adams techniques with digital camera equipment. As an aside, the article was chock full of composition hint's to "capture" his style.
Using a dramatic sky was a major point in several examples, of how to turn an ordinary shot into an extrodinary shot. I think you got this one right! Very good....O.K., now don't get a big head, you're not Ansel....come to think of it...neither am I
In all seriousness, great:thumbup:
