Wow, amazing stuff.
The first one is cool, but feels like it could use a little more something.. but I dont know what.
Second pic is just amazing. I love the reflection on the small ripples, and the light fog, the arches, and the sky, GREAT pic.
Third pic I just think the bridge is ugly, and theres not enough going on in the sky to make it very interesting.
Cool pics though, keep them coming.
