Hi and thanks for the comments, I think I can understand the comments very well.
Somehow I think this still is the speed I want, my teacher also told me often that the music needs to sing a bit more. Myself I also think there is still stuff to work on here. Currently I am busy with the fugue, there as well I need to choose a tempo. What do I have in mind with this piece, I think what I like best about Bach, at least in my memory going over the times that I first started to listen to WTC, I like best all the voices that move in and out, going on and on, and just as you think that creativity is over, there again comes another voice.
Yes, good points about contrast, melody and rhythm. I need to know better for myself what it is I want to express.
Anyway, I think I hope to make another recording, with the prelude and fugue in 1, and hopefully the prelude there will also be more satisfactory for myself, though I was proud of the fact I can play it like I did, as I am an amature, and still have quite some technical stuff to learn.
