I haven't got time right now to listen to it all, so I skipped through and listened to various bits of sections.
First off, I must say that I think you overuse rubati at the beginning of every bar. It is a unique interpretation standpoint, but I think you overuse it. I think if you played the entire piece at a strict tempo, i.e. with a metronome, and then went back and played with rubato (like you did before) but only in occasion, it would sound much better and be much more pleasant to listen to.
Secondly, your intro has promise, but I think it is too over exaggerated. I think if you lessen the time spaces in the opening 3-4 notes relative to each other, then you could keep the same effect but lessen it's emphasis.
Thirdly, raindrops aren't so chaotic with their falling, and yours seem to pause and then splurt out a load, then pause again. This comes from your use of rubato, as I mentioned in my first point. I think it is too over exaggerated, and occurs too often. Try holding back on pausing until moments you think are crucial, like maybe at the end of phrases to indicate a breath (like a singer, emphasising the end of a phrase and the beginning of a new one) or at a climax, again to emphasise and accentuate.
I will have a proper full listen later on today. I hope my thoughts and opinions on your playing motivate you rather than demotivate you. Also, you said you were still a bit unsteady, so apologies if the pause at the beginning of every bar was due to that and not interpretation.
I hope you really get this piece under your belt so you no longer have to worry about the notes and can focus purely on interpretation. I really love this piece and it's great to hear another play it, especially all the ideas you put it into it, they fascinate me.
