I'm impressed you made this on a mobile DAW.
Wishing the texture at 0:17 went on longer... Second listen and I realize this is a snippet of the drop.
Mixing wise, this piece is fairly rough and cluttered, but my-my, that drop is catchy! It's clear you've got an ear for music. I'd have liked to hear that a few more times.
Most of what I have in mind has already been said -- transitions, transitions, transitions. 1:59 I was again moderately disappointed not to be greeted with the drop again. Seriously, love that drop. This piece may have benefited from a true bridge in a different key before returning to our chorus. By 1:39 I was feeling a little confusion -- and wondering when we were going to move on from that riff.
However, theme is strong and cohesive throughout. My only real complaint would be mixing, and I realize this is probably much harder to nail down on Auxy. You may want to look over some general mixing tutorials, as I notice the percussion is especially sibilant, and at some points, like the drop, we begin to see the limits of what the mix can sustain. Bass and lead kind of overwhelm the drums as well, yet mix as a whole is generally sitting about where I aim to have mine for premastering/mastering.
Overall, enjoyed the piece. Pleasantly surprised when I read the words harmonic minor that rather than the usual arab-esque treatise, I hear horror-themed EDM, haha. Nice work!
