Near the beginning of when the horns start becoming more active, I think those are drum hits you have, or some distorted type of percussion or glitch-type click? It was very quiet and I think it could've been be a bit louder. I think the dynamics could be more diverse. It feels pretty consistent throughout and that lends itself to a lack of variety. With this, I think the texture might benefit from being varied as well. After the horn section near the beginning up until the low strings have their moment, the piece sounds very consistent. I think diversifying the texture here and there would be a great way to maintain interest throughout the piece. I really enjoyed when the plucked synth-like sound came in, maybe including that or piano earlier would be good.
Overall, I do like the piece. There were lots of moments where I really wanted to hear a payoff for all of the tension, but it never came. I think giving us one final section that combines the prior elements in your piece and gives the listener the payoff they want to hear would be good. I do see that it is intended to be melancholic as well - I think there is a way to maintain that adjective while also growing the energy. Overall, really nice.
