The water certainly does look chilly. Yet, the image as a whole just does not give me a strong sense of cold. The warm colours and the huge distance with more warm colours say to me that it is warming up, not freezing.
I like this. Composition's great, colors ane nice. Makes me want to be there! You're allowed up to 800 pixels on a side. I am sure I'd like it even better bigger. Probably give it another point.
