hey there, another beepbox user here! The track is somewhat groovy but since you've told that you don't make music often is pretty good. Here some tips for you:
1. Beepbox is a very few features (I don't even know if you can pan the instruments) so I would consider installing cakewalk by bandlab (which is free)
2. If you dont have it yet I reccomend you to get something to jam without turning on the pc (like a piano or something. There are some cheap toy Yamaha piano that are good)
3.If you want to you can learn some very primitive music theory (like chords, "in the key of", scales, Ecc...) that always helps.
Hope my tips helped you!
