This I much prefer to the two Bach pieces. I'm not familiar with the score, so can't say if you've taken any particular liberties. It sounds very much like austere late Liszt (though, unlike some, without any tonal ambiguities) and your performance is quite moving. If I have a criticism, it would be directed at the bringing out of the upper voice, where I think your sound is sometimes a bit sharp when it would be better being more rounded (whilst of course still observing the voicing).
I have a question about your use of rubato. Both in the Bach, and this piece, you use it heavily. Why? Pretty much in the end of every phrase you make rubato. This makes any piece, whatever piece you play, fall apart.I would also suggest you to work a little on your touch. It's very direct, and it needs more variety,
