SOOOO LOOOOONG :000!!!! But seriously, this is very relaxing. But, like Ahurac said, this could use quieter piano. Also, love that xylophone.

The arp is really cool in this one. I think the piano is a bit loud contrary to the drums imo. It's not a problem if you're inexperienced with drums, just keep it simple with kick and snare, add hi-hats and make the pattern coherent with your composition, then you can add fills but it's not an absolute necessity. Be careful btw your hats in the song you sent me are really loud, it cuts the mix. If you want quality drums samples, I recommend you to get KSHMR 3 sample packs, they are focused on EDM but there's a lot of insanely good drums samples included, I highly recommend you to check out. I really love the instrument you introduced at 7:12, it vibes is really cool. Be careful, mostly when your piano hits, the song clipping, to avoid this, you need to mix your tracks at lower volumes, you'll see how good it does.
