This is so nice to listen to! The major two-chord vamp feels so hopeful, especially with the upward piano arpeggios with each chord change. I like the measure subdivision into triplet half notes by the percussion that help give a swaying quality. Your melody is also very catchy and easily singable/easy to listen to. I agree with Peluche that when the beat enters, your chord progression somehow becomes even more magical. Thank you for sharing!
