New Song I Made (I'm Worried About You, So What?)

Hello everyone! I'm presenting to you one of the new songs I have made, https://soundcloud.com/stef-belas/grown-up. It is a main piano loop, high violin chords, a little bit of bass, and a lofi drum track. Several Reaper FX grainier filters with high later shelfs for a more sad and mellow sound/ I would absolutely love to have some feedback, I'm always looking to improve on a musician. The track to me is still a work in progress, so any suggestions or tips would be greatly appreciate. I would also love to hear some of your guys' work and any sort of techniques y'all have used. Can't wait to hear from you all!
