Well, sound design is pretty basic and the sub could be a lot louder. Chords are nice but I'm not a fan of songs in C major because of the natural sound of the key xD.
I like the variation in the drum beat and that reverbed synth that comes in at
2:20
. You should work on giving your track space. Adding effects like reverb, and panning your synths and drums will help with that. Widen your stereo image here bcs rn the trac pretty thin. Make it t h i c c.
