I really liked that! So much so I wish it was a little longer. Very good for one of your first attempts! I don't think I'm good enough to give profesional advice, but if you want to keep using beepbox (the GOAT) I recommend switching to ultrabox or abyssbox. They're mods of beepbox with tons of new features. (Panning, EQ filters, etc.) I'd say they're even near the level of a real DAW. Heres a link to ultrabox. I recommend turning on all the preferences.
