Hmm, already have a nice style here of your own.
The colours on the moonlit stage looks abit off the wrong palette, as it's more of a sunny day rather then a moonlit day, perhaps make use of a darker shade for most of the colours?
Vice versa on the second
Using the same palette for backgrounds for both a night and a day is a rather eye straining for most part, so try and do a difference on them.
The last one looks to be quite well on on the right colour.
Gladly watch more once you've done the small changes.
