Well, the first though I had was "20D!". And i was correct. The quality really is stunning.
I like your composition. Lots of people don't really dare to put most of the emphasis on the ground since quite a lot of times it makes the piture look boring or really off balance. You have managed that well. And It was definitely a good choise because in this shot the ground really gives a lot more then the sky would have. Well done
Very nice. I must say the 12mm makes this pic, as does the wonderful timing. The colors are nice and vibrant without being the focus of the scene. Composition is excellent, with good strong fore, middle, and backgrounds. Well done, my friend.
