Too bad the dog is so small and insignificant looking here. I think it would have made a difference to the impact of this photo if we could have seen the dog closer up frolicing in the snow. Also, what's the pink thing in the background, a car? It's distracting.
This is a really pretty shot - love the dog in the gorgeous snow-covered branches. If this were mine, I'd have selected that pink blotch in the center and desaturated it, given the free-editing rules. Your eyes tend to be drawn right to it, rather than the dog or the trees.
