Help please

I need someone to help me with an analysis for Bach Polonaise from French Suite number six BWV 817.
I have something written,but I don't use quite a good terminology:

So this is the polonaise:

What significance does have Bach's use of non-harmonic tones?To me,perhaps it has a modulative significance because whenever he uses accidental,that's when the piece modulates.
And did Bach broke any ''rule'' or created any exception? It seems to me that he used several times a big interval leap.

Please help.

Bach made the rules so he can't break them.  Haha.

I've heard it makes modulation less jarring if the new notes are introduced gradually -- #4, b7.
