Terrific capture. I'm surprised it didn't do better. Excellent control of the focus and the colors really jump out. The scene is wonderfully interesting.
The thing I thought cool about this one was how it looks like they're kinda in a movie theater transmission of the dam. They're so sharp and clear and the dam looks so far removed from them.
Very nicely done if a bit oversaturated. I think I might have toned the colors back just a touch. Great seperation of people and environment while giving enough detail of the damn to make sense.
