First of all - i love the idea! It's super unique, and i haven't heard anything quite like it so far in the jam.
I also really liked the production. It's overall pretty smooth, and i liked most of the sounds you used. The only problems i had with the production were the trumpet sound you used (as a trumpet player, i'm super picky about how midi trumpets sound, so i don't really blame you), and that sometimes the production kind of fights itself ; around the end when all of the instruments are super loud, it's hard to understand what i'm supposed to listen to, 'cause it feels like there are so many parts, and the part that i thought was the most important is wayyy in the back of the mix.
But again, overall i did actually like the production, but just these hiccups brought it down a bit.
Nice work, and i would love to hear the version with vocals some day :)
