Hey nice job, I will say that the feel you've made with the music definitely matches the concepts you're going for i could feel the depression, i could feel the fear, conveying what you want in music is the most important/difficult part IMO. As for critique, Jofes makes a good point that your instrumentation is very linear, 4 has the most variations, and drive in it, but even there your melody has very little variation in its rhythm. Set your melody, then go back over it and just add some 8th, 16th notes even triplets every other bar in a little run or arpeggio for some variation that won't really mess with the pacing you've set in the OG melody. From a mix standpoint, it always tempting to add that lovely warm bass, but I'd recommend pulling it back a bit on it, as it does over power the few other instruments in there except for 2 where the guitar is the one that's too loud. Mixing is a MF but an important MF. good work over all, keep it up
