I'm not gonna have a ton of critique to offer that I know would be useful for FL Studio Mobile, but a lot of things I notice are just overall mix clutter. The idea itself and the fact you were able to write this on a phone or tablet is great though. Shows how far music has gone.
So, on your builds, when the kick is rolling, pull back the sidechain attack and release so we don't just hear the kick. Hearing just the kick and snare is not what the audience came for
Bass wise, there's a sub under there that's kind of interfering with your growl. On the drop I would at least taper the sub with sidechain to the growl so it doesn't sound like an instrument is dropping out when they're not on the same note.
The rest of anything I could say would be reserved for how the mix is sitting. It's very bass and mid heavy, sounds like from 8khz and up we have a gradual rolloff of highs. I'd like to hear more hihat, a little more compression on your growl, less fuzz, more rounded out bass.
I'd love to see what you could do with a full version of FL Studio on PC. :)
Thanks for coming out to NGUAC!
