The sound design is good. add some processing to get a fatter, or more metallic bass.
Serum is complicated, watch some tutorials, or download some free riddim presets and study how they're made.

Overall a 4.5 out of 5

(ALSO TURN DOWN THE OTT MASTER LEVEL, YOU DON'T NEED 10 OF THEM AND THEN ROUTE THE BASS TRACK TO THE OTT SPAM CHANNEL, JUST USE ONE!!! ~Jk do what you want~)

I think putting monkey sounds in this was not a good idea
