I love it.
So lets approach this from my POV.
You've got a great melody. Once you plop in lyrics it'll be awesome.
a poppy bassline would be killer on this this one maybe a "boom boom bah dah, boom boom BAH DAH (Higher up)"
A doubled ukulele surrounding but blending with the guitar would be great, panned to each side with the guitar having enough reverb to be the glue to hold it all
the drums should be pretty clean and not very touched, also keep it scarce like it is
do some real claps with the synth clap in the back only to add some pazazz, like you can only feel it not hear it
also, keep the rhodes, it sounds great
you've got something really great going on here, sounds like a modern pop hit in the best ways
great work bud
