Feels too contrasty. I'd say try to control your values more, since right now you've got a lot of darkdarks right up against lightlights, and so the eye just goes everywhere. Tyler Edlin has a lot of good Youtube vids on landscape design

I actually quite like your pointy shapes there. If you apply more rhythm to them I think there can be wonderful result

Try to get a bigger separation of foreground, middleground, and background. For example in the first one, the shapes in the grass, mountains and clouds look very similar. They have the same level of complexity and value range. They all fight for attention.

Hey Miguel.these look epic! From life or photo or imagination? Just curious. I do notice one thing in the photo on the right. The path that winds away has some perspective issues unless perhaps i have your horizon line in the wrong spot. Every time the path changes directions they should go to a new vanishing point. I tried to markup the photo with my fat fingers on my iPhone so it’s a bit sloppy. Sorry bout that. The clouds and gesture of the mountains are great. Good stuff.
