Pretty nice track, definitely has some good vibes and rhythm elements throughout. The vocals as mentioned above sound very off, if anything, to me they seem to be off tempo. At the 5:00 mark, the droning vocal gets very repetitive. My first impression would be to do some LFO or gating on them to create movement. Add in some swing and you might have a solid segment/drop/etc.
Overall, was enjoying the rhythm and bobbing along to this one
