1) Like the colours a lot. I may have moved to the left or pointed the camera more to the right to loose that brick ? thing on the left. Then I would have walked to out on the stone jetty and removed that very bright red and white pole Same with the life bouy. ( Probably you would get into less trouble if you just cloned them out 
)
2) Looks a bit dark on my screen at work. Either more or less of the person climbing out of the canoe would have been better.
3) no real comments
4) I think that this is the best. I like abstracts and light patterns.
