Improvements for this environment piece?

[Zabiier]

I recently painted this lanscape from imagination using some references, after doing some landscape studies. Altough I kind of tried my best, I still don't see it as good as I'd like to.
I spent 2h and did it on procreate.

Any advice on what can be improved? regarding color, lighting or anything really important for environment art. Thanks !

I think the main thing that needs to be worked on is the Values. Things are currently to close to each other on the value scale an it makes the piece feel a bit flat. Make things in the foreground darker and everything going towards the background lighter. You can make the mountains in the back a little more blue as atmospheric lighting takes over.
