How could I improve this mix?

hello bro
you have problems with balance - a lot of drums.
The master compressor compress the cymbals heavily.
 
I think the mix has a great backbone, but there are some balance issues. Are you automating? It sounds like you made room in the mix for something else, but it's not there, so the whole mix sounds "out of focus" if that makes sense. I think some leveling and maybe minor eq tweaks and you will have a decent mix.
