(If you could space them and number them it would help alot on discussing them )
But anyhow, I guess I'll just say what i think of all of them.
1. Good shot and use of color and reflections, however i think that a lower angle would have helped and the picture seems to get very glary in the distance, and the red bridge is a bit distracting because it doesnt seem like its the subject yet draws attention.
2. My favorite, love the color on it. Possibly crop out all the foliage a bit but i really like it.
3. Really glary, maybe you could soften the contrast with levels to get a little less hard contrast.
the rest feel like the first, good color but maybe a little different angle could have made them more interesting--or a wider angle lens? Good pictures though if i didn't sound like that.
