yo, love the initial vibe. i think dropping back the reverb a bit when the beat comes in to bring the piano closer would've been nice, give the beat a more intimate feeling. i like the piano changeup at the halfway point but really not digging the big stadium dubstep drums. appreciate the attempt at an emotional crescendo w/ the filters opening up and the open hihats coming out, but it doesn't really stick the landing. the phasey crunchy drums would be good sound for a top loop over the initial kick/snare but don't really have the gravitas to carry such a big change in the overall feel.
structurally it kinda just starts and then goes and then fizzles out. the change halfway is cool but there's no real breathing space at any point. drop out to that second piano part on it's own for a bit, cut the bass out here and there. idk. on one hand the track doesn't really have a whole lot going on but on the other hand it has this really abrasive drum switch in the midpoint which could be cool but isn't effectively capitalised on. and i think i would prefer a simple idea really well realised to an ambitious gamble that doesn't quite pay off.
i will also say though that i do like the highpass filtery transitions - just needs some other element to really sell the tension and release between sections. the reverb fade on the drums at the end was also really nice. also the flutey synth line in the first half is very nice and it should make a more prominent return.
tl;dr - make the second half more like the first half but keep the cool synthwavey leads and pads, and add more small details in the arrangement and structure. it's most of the way there! thanks for doin' the nguac :)
