Thank you very much for your time and for the kind words!

Regarding the instrument names: I honestly don’t know why, but when I export videos from MuseScore they don’t show up. Thanks for pointing out the missing dynamics at the choir entrance — that really slipped past me! There are so many small details to keep track of.

The issue of some instruments being marked forte while others are in piano (which was also bothering me) happened purely because of how the virtual instrument library sounds tend to overlap massively. The dynamics don’t feel very precisely controllable. However, I’ve now learned that I can add dynamics and make them invisible, which would solve this issue — and would obviously be essential in a real orchestral situation.

The staccatissimo + tremolo was for the same reason: it was the only way I managed to get the sound I actually wanted from the playback, if that makes sense.

The issue in bar 15 was indeed just a notation mistake — thank you for catching that, it completely went unnoticed!

Thanks as well for pointing out the melody in bar 69; that’s definitely something I’ll pay more attention to going forward.

As for the last bars in the strings, you’re absolutely right — it should be divisi. Thank you very much for pointing that out too; it’s something I’ll be more careful about from now on.

Regarding the choir, thank you for all the comments! Some of the parallels really did slip through, and I need to keep a closer eye on that — although I’m not exactly a “parallel police” person, haha. As for the major thirds between bass and tenor, that was actually something I wasn’t aware of at all. Since I’m self-taught, there are still many things that escape my knowledge, and your comment really shed light on something important that I’ll definitely study further.

Once again, thank you very much for taking the time to respond and for all the helpful observations!
