Hi georgey,
Very nice playing, and Happy birthday in advance!!!
You should be able to get the prelude in without any problems, it's the easiest

But the fugue is pretty hard.. It's a four voice, plus it's in C major. C major is actually considered the hardest key to play, because it lacks black keys that you can shape your hand easier on. And I think you have dealt with it very well. Mostly every note is clear and audible. I could've used some dynamic contrast here and there, but when it comes to playing Bach, half of the audience is going to disagree with what you are doing no matter what you do. That's why playing Bach is hard.
I notice that you are playing the eighth notes legato and the sixteenths sometimes nonlegato, but it should be the other way around. Generally, eighth notes are separated in Bach.
Happy Practicing,
Natsu
