Thank you, by that I meant that I want to see the criticism of the work.
As for the lack of going beyond the key of Cm: we can say that this is such an experiment, the purpose of which is to check whether a full-fledged work can be written within the same key.
I probably confused you by posting the music at 11:46, but in fact the clean piano ends at 06:23, and I really should have posted the music only before 6:23. After 6:23, we can assume that the arrangement is in progress, as far as it is appropriate in this music.
Thanks for the feedback
