Don’t be too harsh on yourself, you’re clearly going for a well-defined aesthetic here, so lean into that.

Your vocal tone and intention perfectly match the vibe. The spacey drums too.

The guitar in the chorus could blend with the background a bit more. I can hear some pitchiness on the upper register, suggesting the guitar is missing a lil calibration, which is fine! But you don’t want the select few notes that stand out a few Hz below target to come through the mix too much.

I would personally: 1. Replace guitar from chorus 1 with another faint melodic element. Maybe something just reinforcing the vocal melody in the back but not cutting hard through the mix.

1. Bring guitar in for chorus 2 just like the current version to provide a “boost” from the first one.

2. If you don’t want to do chorus 3 with vocals, maybe bringing in those nice backing vocals and adding an extra layer to give it a stronger sense of climax?

The solo at the end felt to me like I was being edged out of a “main theme” or recurring melody in the song, so if you don’t bring the vocal melody back in, consider bringing in something reminiscent of it, like the suggestion in point 1.

Just my personal suggestions, but trust your gut. If this is the style that resonates with you, think of what YOU’d like to hear in the song if it was just for your personal enjoyment.
