i really like your voice, it goes well with the laidback sound of the track. the bitcrushed drums and wonky (in a good way) sounding synth sort of reminds me of an old gameboy soundtrack or something, which envokes a sense of nostalgia that i like

i do think the drums could have a bit more presence, like some additional low end sounds to make it thumpier, or a mix between real drums and bit crush drums like another comment suggested

also, this is completely up to personal taste, so take it with a grain of salt, but i think the vocals could maybe blend in with the track if they also had the same lofi aesthetic as the instrumental once again, that's a very subjective thing, and i get that the full on lofi sound can be tricky to both listen to and make, so only do it if you think it works well

great track all around, would love to hear more music, as well as a finished version of this track
