How do I improve these clouds?

[stable mirage]

Im in the middle of cleaning up my sketch and I noticed that it doesn’t fit the background at all! I have zero idea how to draw clouds/ how to make them look like they fit in the scene. If anyone has tips or advice it would be very much appreciated. And if anything else looks off please point that out as well

Maybe if you make them a lil bit more blue, idk

maybe the top right clouds should be angled a bit to the left downwards
