Very nice light, good scene and capture. I like the larger tree as a framing element here, though it took me a whilke to realize that this was all water and not sky for some reason. As such, the water is interesting enough in shape that I'm not sure the tree is needed in this shot. (And the little tree or branch bottom center would be better removed through cloning in my opinion. Overall, I like this very much.
The centred branch detracts from what is, IHO, a truly great image. The sea texture, the gulls, the ice, the whole works so well. I'd have this on my wall. Maybe the tree in the foreground could have more character, on further viewing. 9
The idea of this image is quite interesting, but I think that the composition is a bit problematic. The branch that intrudes into the frame from the centre bottom of the frame is very distracting, and I'm afraid that the shape of the part of the tree you've used to help frame the image on the left is a bit awkward, unfortunately.
