ranjit hey, did you want feedback? I think you really need to work on your dynamic range and really put your weight into the keys when the f/ff/fff calls for it. I see that in general you play very on the surface of the keys, you have to play the section with the opposing octaves like you mean it! And even for sections where you don't need the hand weight for volume, playing into the keys gives you gravitas and character. This is piece has a lot of serious themes, probably dealing with war and death. If you fly lightly over the keys, it just sounds frivolous to me.
You had some nice phrasing in the first page that I liked. I had been working on this piece for a while but set it aside for now; I think I need several years to really do it justice. This is really such a beast of a composition!
