off tempo guitar and delay + too “washed” (reverb) string section + 0:35 melody change is not nice (too high in pitch), 0:51 you try to develop your track but you only add another non usable (no purpose) layer to it + mix is too washed too muddy (~200 - 500hz + ~800 rezo frequencies) + guitar also idk why, sounds like you low passed it, you cut so much high from it.
Composition and arrangement at idea is ok
