I agree with the others: HDR does not really show and the light looks like it wasn't really necessary, either. How many exposures and how far apart did you use for them?
The second looks a little soft, or as if the lens had been fogged up, is that the effect of your merging three (or so?) exposures?
The layer of clouds and the mountains in the last are really interesting to look at! And you have a real WINTER. With snow and all. Wow. We haven't seen a single snow flake as yet all throughout the months that normally are considered winter months ...
