I find it a very deep and interesting work.
But I have to say two things:
I think in many parts there is an excess of textural density. There are moments where up to 8 voices are counted. Especially I think that systematically doubling (octaving) the bass-pedal, and also some upper voices, brings confusion. When the voices are simplified it sounds much better. In fact there are parts where the intervals between the lower voices are intermingled.
Although the piece sounds good and smooth, and has a certain flow given by these changes of texture, it does not have a very defined structure. This, in a classical-romantic context, has to be taken into account.
Cheers.
Great work!
