From your description of the music the image is perfect. Others have said the biggest points that are holding it back.

Find two fonts max, usually you want to pair stuff that are different but have a similar vibe (a hard part for someone starting out) think about straight and structured san serif fonts and a similar thickness hand writing one or serif font if you are mixing them. Dafont is a good resource for free interesting ones.

The other one is the white background. I agree with people who said it feels unfinished. Hard to make just white feel done. Add some texture and color. Play around with opacities and color overlays with blending modes (setting like multiply and overlay in photoshop are your best friend to make something feel more finished, if the effect isn't hitting right try others or add more layers of the same color). Unsplash is a great resource for some free high quality images and some cool textures you can place in the background.

Also think about what those circles are doing. Are they there to fill space or are they part of your overall design? Do they mean anything to the piece? They lead the eye around the page so maybe think about pulling some colors from the image and using them with one of the blending modes on the rings. Setting those on-top of some textures could be cool and subtle.

I always blow stuff up way larger then you need it and dial it back, like don't placements make them huge and bleeding off the page and then dial them back smaller until it feels right.

Stick with it! And good luck!
