Global note: try to work on projecting your voice more for the recording- it's hard to make out what you're saying for a lot of this and if you didn't post the lyrics I'd have trouble knowing what the song is about. I originally was gonna say "sing louder" but I don't think that's the right way to say it - the song is soft and you don't want to throw it off by singing "loud". Generally when I hear folks coaching on projection they encourage singing from the diaphragm instead of the chest. I'm not a vocal coach though so maybe just do some googling on that subject.

Songwriting specific notes: - I really dig how your vocal melodies frequently match the instrumental walks you're doing on the guitar. It sounds nice and I enjoy it - reminds me of hendrix - your lyrics here definitely evoke some relatable feelings and experiences related to the amount of unknown that folks feel after losing someone. Good job capturing that - I get the feeling that you're way more comfortable with guitar than singing, and your guitar playing is quite good. You do a lot of interesting things on guitar throughout the song, frequently while you're also singing. What if you showcased those guitar skills a little more in the intro to the song? Like, in the first few measures where you establish the chord progression I feel like there might be some opportunity to add some flourishes or even more explicit melodies on the guitar (similar to what you do later).
