Yes, it is amazing you've only been studying the piano for 2 years. and that you are drawn to this most incredible piece. You must be an interesting person to get to know!
You have definitely understood, I think, the very funereal character of this piece. And bring it out very well. I don't know whether I read it here or some place else or if it just came to me now, but that is the dies irae theme, isn't it. You see, you made me remember that or made me hear it!
you have caught the spirit, but you are playing around too much with the tempo and dynamics. I'm not one to be pinned down to the printed page, but if you are going to take liberties, there has to be a reason and an outcome. I didn't hear the outcome. At times it just dragged and dragged and lost the flow. And you hammered out, at times, that theme like a death knoll. Which it probably is, but it's all sotto voce. THEN when that majestic march-like theme in the middle arrives, it should sound like some sort of victory. Maybe victory over death, i don't know. But you distorted that drive and impetus by playing around with the tempo. I was beginning to think maybe you weren't sure of the notes - could that have been it?
At any rate, I can hear you love this music. But you've got to make us love it, too. And it can't be such a personal and private interpretation that we can't get what you're "driving at".
