Visual chaos, hard to look at. In #2 I actually have no idea what I am looking at above the "horizon". Is that sky, or a farther-away snowy slope? What's going on? The contrast is so high that everything seems to be rendered from the same palette which consists of: Black, Pale-Sepia. Technical problems abound, with halos all over the place.
All that said, they are all basically the same composition, and it's a good one. The eye is nicely led down an interesting stream bed to a pretty good place in the frame, and contained there by the masses of rocks. There's a lot of great textures lurking there in the chaos, and the larger masses are placed nicely in the frame, once you sort out where they are. I think these could do a great job of conveying a mood if you toned down the processing and thought a little more about what you want to convey and what kinds of effects might accomplish that.
