Looks like you did a good job of applying color adjustments that look close to a complementary color theme. I don’t think it works well for this image however that is must my personal taste and I’m sure others will love it.
I agree that it is difficult so apply so that the image still looks either plausible, or a deliberate effort to make an artistic representation. For me this is somewhere in the middle, but I’m not sure what I would do differently. Maybe make the blue more subtle and let some whites appear, and/or some more detail in the rear mountain range?
