Arrangement wise, this is a fun piece. Mixing is killing it though.
Snare is all the same velocity, and I can barely hear it. It also sounds like it's got an insane low rumble.
Bass drum/timpani is very loud, flat, sounds like it may have been recorded in a shower cabin. Take the volume down some.
Triangle is slightly too loud.
Clarinet/oboe needs to come up. Bassoon needs to go down.
Watch the velocities on your individual instruments. I think they're machine-gunning.
No score reductions for track length, since this is intended to be a short piece, but definitely see some mixing tutorials for your chosen genre/DAW. This sounds like a fun piece -- one I would probably like to play, myself, but the mixing and velocities shoot it in the foot. Fix it and I'd give a straight 4.
Thanks for coming out to NGUAC!
