if you want feedback, id recommend using more automation, particularly volume automation. at least in this song, it plays a lot with dynamics, and that can be aided by changing the volume in the calmer parts. the outro could also benefit from a lower volume, or maybe a low pass filter of some sort. also, it´s important to mix and master your tracks. the tuba'like synth is quite overpowering in the mix, and is compressing most of the other instruments whenever it plays. otherwise i love this song
