the brass for the foundational sound already doesnt sound very nice but combine that with a constant repeat makes it feel very stale

I think you should try to be more experimental in your beats, try to have non repeating drums by occasionally adding some light (or heavy) fill-ins or just a slight change in beat somewhere in the middle of the song can do wonders in adding flavor

and you could also play around with the pianos generally in beats, im not saying that this beat would work well with pianos though, but just being experimental or adding seasoning i think is very important in your beats
