your 808 is quiet as fuck in the intro, probably intentional. i'd add some type of progression with your vocal chops to give the intro more of a character

the 808 in the drop needs more of a sine sound and less of a harsh detuned saw sound. probably like 90 to 10 ratio. the bass hurts my ears.

vocal chop doesn't work with your drop imo, I would try and find something else.
