I'm going to try and give constructive criticism, so this is not to bash your creation or anything.
I'll start with what I like.
The Percussion. Despite what you say about ambient bass being a joke, that is some pretty solid ambient percussion; if you were trying to make some chill future bass, you're definetly heading in the right direction.
Overall Arrangement. The piece keeps moving, which keeps it interesting. It's not a complete loop which is good.
Okay, here's what I feel could have been better.
Future Bass. You've got like nearly all the elements of it (the quick snares, the hihats, the vocal chops) but there's no bass! (I'm wearing Beyerdynamic dt 770 Pros and I can barely hear the bass) It's kind of ironic. Try adding some 808s! (Make a low sine and then use an envelope to modulate the pitch downwards very sharply
Chords. Most Triads are fine, but you can spice things up by adding 7ths and 9ths. Don't be afraid to experiment with some jazzy or wack chords you've never heard of. If you're looking for some thickness, try detuning them after adding some unison. Don't forget to modulate them, it's almost like a staple characteristic of future bass (you don't necessarily have to make them "wub" in a sense, it just has to be a bit off beat if you get what I mean) I don't know if you've heard of Subtact, he does some solid FB. (Subtact — Restart is a good example; I'm not sponsored and the artist isn't me, I'm not advertising, it's just a good example)
Rhythm. Future Bass is a sub-genre of trap — which is known for NOT fixing to the 4/4 time beat pattern. So experiment! Get funky with how you feel the beat, just as long as you end on one every time you'll be fine.
But hey, this is just coming from some random guy on the internet, so don't feel inclined to do what I've said.
Cheers! :)
