Nice arpeggiating with a very real sounding piano. Hmmm...it's an okay prelude in my opinion. I personally get bored of arpeggiating rather quickly, but what I think could be improved on is the sudden end to transition into the fugue. I think it would work better if the prelude at least ritarded a bit before suddenly stopping. That way the listener can expect the fugue easier. I even think a little more creativity on that half could be beneficial as well. The fugue itself is nice, just wish I could hear what happens next...I like your transitioning from minor to major, just like Bach does, so I'm expecting you repeat the theme in a major context after that. Overall, this is pretty good, I just wish the prelude was a little more humanized in a sense. But nice work!
