Thanks for posting your examples. It's quite a lovely scene.
I had a couple questions regarding the burning sequence you've described. Are you using the same contrast filter as the main exposure for the burns? It looks like the foreground water was burned in using a lower contrast filter to bring down the highlights without pushing the tones in water down too far. Retaining detail in the background, which works here without competing with bright rock textures, can be achieved this way too.
All the best,
