Love the opening swell. Sense of mix is pretty decent, maybe a little murky and narrow, but otherwise very good.
The second section definitely reminds me of Shostakovich, which I can really appreciate. I feel like the buildup doesn't quite hit in the next section because it could probably use some double bass to really deepen the sound. If you look at your waveform at 2:16, the waveform is bigger than the climactic moment. The composition is good, but it definitely needs that punch. But, I really like the composition and love that it reminds me of Shostakovich.
It gets a little repetitive later on, as another person mentioned. I think that this is also indicative of the fact that writing classical music is really fucking hard, so definitely don't take that the wrong way, I'msuper impressed with your composition overall.
Do you have a midi controller? I feel like you should play some of this more organically.
So, constructive feedback:
Some of the instruments still sound a little artificial, and the mix is maybe a little dry and narrow. But, the composition is really cool, and the approach is definitely more challenging to pull off well, and I think it got a little repetitive, but in general it is very good and indicative of a lot of skill.
Well done and thank you for your entry!
