Hell, yes! The omnichord might be a little loud in the EQ range, but the very fact I'm writing that shows how little I know when it comes to mixin' and masterin'. Anyway, a lovely tune and a good strong vocal that carries it over the minimal chordal structure of the song. However I didn't really hear the challenge being met, so you may lose some points there ...

The emotional core is here, but there's a lot more iteration left to do for you to figure out the arrangement and melody. Your vocal performance is halting, and I don't get the impression that it was a conscious performance choice. I'm also not wild about that omnichord tone, but I guess that's a personal preference on my part. You're playing mostly whole-note strums on it, but still managing to not quite land on the beat. If you do want to develop this idea a little more, consider what you might do with the long gaps between lines in the lyrics. I'm not sure that the current strategy of leaving them empty is helping much. You might increase the tempo to lessen the effect of those pauses, but I think maybe some instrumental ornamentation would help. Or maybe filling the gaps with some call-and-response backup vocals? Right now, I have this feeling of "Come ON, get to the next line already!" which probably isn't what you're going for.

your voice sounds great on this and I think the song as a whole is strong, but on repeat listens I started to wish there was a little more going on in the arrangement. If you're going 100% omni then maybe something like a second track with some delay on it coming in as the song progresses would be cool? But I liked this one.
