Cool, I would say very very cold. The only color in this image, is that of the fence, plus the many, shades of white everywhere else. I like the emptyness feeling about this image, well done.....
I know this place so it probably effects my vote (high) but I really like the difference between the monochrome background and the almost tinted foreground makes a very nice study. Good job.
Interesting parallel line work you have going on here. Lighting is a bit drab though, and other than that parallel thing, there's really not much else of interest.
Love the pop of green in the foreground against the soft,misty background tones...restful, serene, a pleasure to look at. One little nit pick - I may have cloned out the tallest twig to the right as it bisects the dock in a way that's a little distracting. A very lovely image...good luck!
There is a lot of the top of the frame which is wasted I feel, it's just a bit empty. Maybe a closer crop or one further down would hold more interest?
