the main piano melodies are very good; i love how thick the piano sounds! the buildups to the drops could use some more emphasis, like the risers or snare fills typical in edm. the way you've layered rhythmic loops here is very nice. i really like the saw chords that appear in the middle of the song! the mixing is decent here. maybe this song could use some more variation or sfx to make it even more engaging, but what you have here is great!
