Hi Franz,
First off welcome to the Landscape Critiques. This is a lovely image with wonderful atmospherics. The fog has graced this scene with a peaceful vibe that is very inviting IMO and the diagonal of the riverbank also quite works well. I do think that @Bonnie_Lampley rework with the small tweaks has elevated an already beautiful image another notch. I think that one has the most natural look that you were striving for. Beautifully done!
