I do love what you have started here! To be honest though using that piano from nexus is a risky move sometimes lol. I have a track I made a few years ago with that exact chord and sidechained the same way so I actually thought this was one of my songs at first lmao. I would say you should try and get creative with the pianos, they're not necessary and can always be replaced by pads of sorts. I love the pan flute you brought in though! The portamento on it is a nice touch, the melody is also fun and fits the bill of the vibe you were making here.
Overall, I would say just try and expand your library of plugins and such. Also, nice lead layering with the pan flute! Very good touch. Though I don't think that kick fits this type of a song to be honest.
