the intro - hats off! (5 stars)
melody - great (4.5 stars)
build up - the snare was really something that hooked me up (5 stars)
drop - this was the only thing that I personally didn't like, I was really missing the hard kick throughout the song! I thought the kick will start sometime soon but I lost hopes after 2 minute mark. The vocals were great, those hats need some more mixing work though, the kick is almost inaudible, while in techno, kick should stand out of the mix. I also think you should've added some sidechained synths at the drop to fill out some empty spaces. Also some pads at silent places would've worked great.
Pretty decent track overall, keep it up!
