These were handheld shots. Which is what prompted the "difficult captures" comment. Most of these are with me using a timed shutter and holding the camera, bent over with my arms hanging and the camera held with two hands, inches above the water surface.
They were not sharpened at all. I think the details of the rocks actually take away from the overall scene in this case.
Braineack is right, the "fuzz" is from postprocessed blooming. I can certainly see the "overcooked" feedback. I edited these with the intention to look dreamy and artistic rather than be highly sharp representations of reality.
Here are the first two, with only RAW exposure/lighting tweaking done. And a much more lightly cooked version. Y'all are welcome to edit if you like.
