I really like the huge depth of field in this photo, and the patterns that the docks make. The clouds in the sky somehow look pretty unnatural to me, but I can't quite put my finger on why. Overall a really nice photo for this challenge.
7 - Very nice. Criticism; not much and difficult as I don't know 'what is there' either side, but perhaps a different crop, especially with less sky, may have made this even better in my opinion. Like the 'straight lines' in the docks and far 'land'/causeway.
Interesting shot. I think it might work better with more sky cropped out. It would give the repetition in the docks(?) more punch. As is, the sky dominates the frame, but it's much less interesting than what's below it.
I love this shot. Though I'm by far not an expert I would maybe suggest cutting out maybe a quarter of the picture on top, even though it may go against the rule of thirds, but speaking of that rule of thumb it seems to be in effect vertically too. I still like it a lot as it is though.
