A very strong left hand if you used the strings you have described. If I can tell you little suggestments, sometimes you have choosen too difficult fingerings, expecially in the first part, with a lo of use of the thumb moved back. Praeludium is not so complicate! The result is a not so good tuning and to use three strings instead of two. Also in the final part. Then try not to change tempo in a rapid manner: Bach was simpler. WIth good fingerings and a more relaxed performance, your Bach will sound great! You have all the technical characteristics to play it much better.
Only one thing. With Corellis it much simpler to play Bach, expecially with low tension strings. A lot of great performers switch to them, also to have a similar cello sound. But it's a question of choise!
You are on the right way. Bravo!
