Excellent. This is my big Bach piece ( need more I know) and I enjoyed your interpretation, your phrasing is excellent, elastic so that the music breathes. You play some rythyms in the fugue dotted, guess you have a different edition (I use Henle) and a note in the 4 vox fugue you play g natural, I play g#, but we all know about me and accidentals...
I like more variety of tone color in my piano Bach but that's just my personal preference. Your articulation is very clean and precise and differentiates the phrases that way, which is more Bachian than using dynamics, which were limited for Bach's keyboard music. I particularly enjoyed the 3rd mvt., it's very difficult to play on the piano and you did it great! Think I'll go listen to your d minor Toccata, that one's not played so much.
