The first one is great. I love the simplicity and four distinct parts: sunburst, tree, water, and mountains. They're combined nicely. I love elemental photos like this that only contain some of the basics of Earth.
There is a repetition of triangles - skinny triangles laying on their side. There's a triangular dark patch of clouds on the left, a wedge of dark mountains on the right, and a triangular pattern of waves in the water. This is very pleasing.
Personally, I don't care for the "artistic" treatment. It's just not my thing. I'd love to see this scene closer to as it really looked.
But that's just my own opinion

The elements you've captured here are great!
The second photo has a great layered look: pebbles, waves, water, sky. Each layer is distinct and stands out well. I love the hint of color, although it's a little skewed from reality (as the naked eye saw it). IMO, of course. The look of the photo is more of a dreamscape, and in that sense, it works pretty well.
