An inviting perspective with clearly delimitated planes and some strong lines. I would just open the shadows just a tad in the darker areas (the two slopes in the FG at least, possibly also the cliff in the BG).
This had to be a challenging capture and for processing.
Great comp with excellent layering of light and tones and a neat zig-zag progression through the image (which, for me starts at the top, although the water would more usually pull my eye deeper from the bottom.
I think Santiago's suggestion is worth experimenting with. But it is also fine as is.

I'm not an expert, but I find the composition excellent and the tones well balanced given the difficulty of capturing two differently lit scenes. I can see the bright background, then look down and follow the river in the darker area. Nice image.
I'd still follow the advice of people with more technical vocabulary though
Nice depiction of the area. Must be a bit downstream of the actual launch area. I really like the comp, and think the shadows could go either way. Still detail in them.
