Yes, totally understand the colour limitations issue.
Okay, well that new screenshot looks really good. My main issue was the green in the mountains. This new iteration, without the green, looks very stylish to me. This is the best version so far.
But again, that is just my opinion. In the end, you are the one who decides what you prefer. And there's only so much tinkering a person can do! In any case, as things stand, those mountains look really impressive to me.
