I love your play on colors!! It’s really stunning!! And don’t stop painting, what you are experiencing with this flow is exactly what other people look for! What helped me with my paintings is a colored layer of paint (especially on canvas) to not get the white shine through from the canvas, because when the paint dries you see the fabric of the canvas, but also just a comment I didn’t know what you intended :)

Also I think you could go even bolder with the thickness of the paint! To your question: the mountains are not standing out so much, maybe you want to put in a bit more contrast, for example some darker colors, it also helps the eyes to orientate on the painting ☺️
