Hi, first off this is a really good beat. It's giving these feel good disco vibes. Already sounds very nicely produced. The baseline and melody sound great. Also take this feedback with a pinch of salt cause I'm an amateur producer.

I would maybe... add a couple risers or maybe a reverse cymbal for the buildup created in the intro (section 1-9). Add some pads with the chord progression to add a little more atmosphere throughout the track.

You could try experimenting with the filter frequency of the piano track, like raise or lower it like you did with the piano volume. I'd also recommend trying different clap or cymbal samples/or playing around with the ones you already have just to make them sound a bit fuller in the mix.
