Thanks for the feedback! I will adjust levels to manage a better relation between the buildup and the drop. ¿Would you recommend adding more variation in the melody on top of the notes of the chords? or ¿Are you suggesting to add a completely new melody?

I like the beginning of the track where the chords hit for the first time, nice. REALLY COOL. I think you should work a little bit in the dynamics between the buildup and the drop, I actually feel the buildup is louder and that's not good. I would lower the volume of the buildup and add a sub or something to the drop.
Watch out for the distortion  between 1:52 and 2:01 on the piano.

After a while the melody feels very repetitive, you could fresh it out by adding various melodic elements throughout the track.A few ideas come to mind (vocal cuts, synth melodies, even a bass hook or something).

Overall it is a nice track, really reminds of of avicii and a little bit of martin garrix. Keep working on it, it has a lot of  potential.
