Hello Richard - sorry I'm late to the party on this one; been traveling last month or so. I'm very happy to see you taking on a Chopin Prelude!
Mostly I like the balance between your LH and RH, and you played all the LH notes evenly from what I could hear. Nice job.
Adding to some earlier comments, for me I found the tempo a bit too fast. It is a matter of preference of course, and I could learn to like a faster version as long as it doesn't feel "rushed" - a subjective line I know!
Early in the piece, when the melody repeats itself in several adjacent measures, I always try to give each measure its own character. To me, and it was probably an teacher of mine from a long time ago that said this, Chopin wouldn't idly just repeat the same measure. Something to think about as you shape the phrases.
One of the downsides to [perceived] rushing is that it takes away from the intensity of the climax of the song. Another thing to think about is to build that phrase a bit more dramatically, and then die off into the end of the piece more decisively.
Nice job overall!
Matt
