Helge, I think you have a nice composition here, and with the haze and repeating ridgelines you have all the ingredients for a good image. But I do think your processing has taken contrast a bit a too far.
I would like to expand on @Nathan_Klein comments. In real life, things in the landscape that are closer tend to be darker and sharper, and things that are further away are usually lighter and softer (less detailed). Our eyes are used to seeing the world this way, and this is what most people perceive as natural looking. In Nathan’s rework note how each ridgeline gets progressively lighter and softer the further away it is.
Alister Benn discusses this concept in depth in his “Luminosity and Contrast” ebook and videos, if you are interested in hearing further discussion on this topic. Alister did a free webinar for NPN, link is below
