The added tree variety is definitely a good improvement, especially in terms of scale variation.
Clouds also work well, exposed photographically, though if I were post processing this myself I'd want to pull back the highlights a bit as they're a little blown out (but again in a single exposure of a photo, they probably would be blown out). I would expect the clouds and snow to be at more similar brightness however, and the snow is actually quite a bit less bright, so that's interesting.
Last thing, there's a bit of a greenish or cyan color tint to the image now, whereas before it tended more blue. I'm not sure it's worse-off for it, but I did like the bluer color tone overall I think...
Still, a great image despite these small niggles, which may come down to personal preference.
