Looks like a heavy dose of topaz... a little too much for my tastes, and also appears on a slight slant from left to right which I find the tiniest bit off-putting. I think I would have scored this more highly with the horizon level, and the large tree on the right sitting on a third. I just don't like the way the sky through the tree is a lot lighter than the rest.
Nice scene, I particularly like the benches in the snow. I feel like this was slightly heavy handed in the post processing, causing some unpleasing halos.
