The prelude is played fast and in the fugue I did not heard flaws (but did not play the fugue myself).
No prelude and fugue from WTC is really easy, so congratulations first for the achievement.
Some minor observations / subjective opinions however. For my taste, the prelude can be played that fast, but it could sound way calmer. In bar 3 RH something in the last three notes and bar 18 RH the 4rd last note sounds different according to my Urtext Peters score. You mastered the RH/LH parallel parts well, but on some places it could be more evenly.
Whether the fugue is played that extreme staccato for the 8th notes like you did is highly a matter of taste. It is not my taste, and I think, Bach did not group the notes by accident, it was intention. For instance, to articulate and phrase accordingly. It sounded a bit harsh to me too.
I liked your ending here, and I thanked God that Bach made some slurs so that you had no chance to play the remaining notes staccato too.
Just a single opinion, and technically seen (beside the personal taste) the execution of the prelude was convincing to me, and the fugue was very convincing to me.
