I Like them for these reasons:
1st edit the best photography wise. I like the clarity and the final tonal adjustments.
2nd photo is almost same but I think the 1st has the edge over it.
3rd photo looks more like low tide to me. The edit looks like little fishes.
4th and 6th both look like painting more than photos which I like.
5th one is very creative and the edit looks very much like light / glistening waters.
Overall I'd still go with the 1st one :)
