I really like the fifth one. The ice is awesome next to the rocks.
Number two is my favorite. I like the streak in the sky, which creates an opposing line for the landscape.
i like number two. it seems like a contradiction showing such a beautiful landscape that you want to explore, but a man made structure making it impassable.
Number two - beautiful parallel between the jetstream and the line of wheat, even to the extent that they both finish on the same vertical line. Neat. Where'd you find number three? That's pretty awesome.
Number 2 is awesome. I love how you can see the the slight breeze in the wheat. The lines are so perfect and the gold color next to the blue sky is great.
I really like the second one. I like the juxtaposition of the streak in the sky created by something so man-made with the landscape... the lines are nice too.
I like the third one best. Nice range of values, and good choice of composition with the sign in the foreground.
Cool pictures. How did you get them to appear so long? That really adds to the effect, especially with the pole and the stalks. Great work.
