nice work! It's like some sort of distant dreamy vhs memory. I recall driving through Cali in a vintage convertible even though I've never done that.
The major 7th you go to in the bass on the I chord (the 2nd chord in the intro-type progression) feels *really* dissonant to me. I like the melody you have in the bass part, but I'd consider popping that up an octave or two and then using the actual bass to hold down either roots or at least more stable chord tones.
Love literally everything else. This is great!
