i dig it! i love the melodic content, and definitely the kind of track i could see closing out a beach party in Ibiza at sunrise.

no real complaints on the mixdown, though i think the accent clap you have on the fourth beat feels a bit off (maybe you could have EQ out some low end or pitch shifted it a semitone or two up?). You have a very good sense of song structure and harmony, and while a lot of your sounds are fairly generic and simple that's in many ways a positive aspect to the song - they don't try to call attention to themselves, and allow your musicality to shine through.
My two main points of critique are your mastering and the flow of your song.
Without compromising the very dynamic and chill nature of your song, I believe you could have gone a bit harder on your mastering than you did. It's not quite at a level of commercial loudness that really helps the track feel complete. You could compare your songs with that of Kygo, Above & Beyond, or Autograf (or whatever other contemporaries you wish) and find that in general, theirs can be quite a bit louder and still maintain the same vibe you're going for.
I also noticed that the different sections were pretty much cleanly divided between one another - your song goes to the intro, then it goes into the breakdown, then we have a bit of a buildup and then the chorus enters, then it goes into another breakdown, then we have another bit of a buildup before the second chorus, and then it enters the outro. It feels like I'm on a tour bus where i'm being presented these sections one by one with very little connective tissue to relate them to each other. The sections are also mostly identical, to the point where if I started playing at a random point in the song I don't think you could reliably tell me where I am. You know that there should be some sort of warning that the chorus/drop/main dance bit because you have a white noise sweep and it feels like the sounds are approaching a climax but it's so subdued that the chorus is actually somewhat abrupt when it enters.
For your next song, try to incorporate some more fuzzy boundaries, and don't be afraid to hold the audience's hand through the track. Use things like risers, downlifters, drum fills, noise/volume/filter sweeps, crash cymbals, and drum fills to announce that we're at the end of one section or the beginning of another. Introduce sounds a few beats or a few bars before the next section, or have them finish after a section ends to help maintain continuity between sections. Also take some time to study how other artists construct their songs - see if you can start to pick out the progression from beginning to end. Maybe the first breakdown of a song has no bass or percussion, and the second breakdown adds a sub layer and a shaker loop. Maybe the first chorus is more melodic, and the second chorus is more bass-oriented.
These little tweaks allow you to stay with the classic ABABA songwriting style while constantly providing something new and interesting for the listeners to enjoy - and makes your song more like a story and less like a tune, which is much more memorable.
Can't wait to hear the next project!
