I'm not an expert on mixing myself, but I would say that's your biggest problem here.

Your instruments all sound like they're playing at the same time instead of "together." THat's a real esoteric criticism, but that's the best my own knowledge lets me describe it. Part of the problem at least is just HOW LOUD THIS IS. IT'S LIKE IF I WROTE THE REST OF THIS COMMENT LIKE THIS.

You want more "room" between instruments so you can highlight the parts you want to the listener to focus on, like when your leitmotief shows up or when you break things down like at 01:11.

I like the core idea you had here, but there's a lot of discordant bits that don't feel like they were intentional; notable examples between 00:30 & 00:40, and much of what's after 01:22.

Discord can be great, but you gotta make your intentions clear if you're using it intentionally.

This could definitely be the intro to something pretty cool, but yeah as pointed out already, it's just 6 seconds of audio.

The colors and freckles on wizard reminds me of strawberries, and that's really cute.
