Dobby says that this is even more interesting now with all this speculation...

Here is the way Dobby sees it. The original is a good exposure. However, there is a green cast to it due to the fact that this was an early snow and there was still a lot of green showing through in the environment. The color adjustment you made enhanced the reds which in turn overpowered the greens, but did not truly compensate for it.

The nik filter gave the overall image a nice feel, but IDHO (In Dobby's Humble Opinion) blew the whites out in the center of the image as there is no longer any detail or definition between the snow on the main branch and the ones behind it. That detail is there in the original and the curves adjusted versions.

Is losing that detail OK? That is up to the Master to decide. Dobby is just a poor lonely house elf...
