That's quite interesting!
Some notes on the score, cause I can't sit and play through right now to provide further thoughts on the playability, etc:
1. The triplets in page 2 and further could actually be 6plets, thus avoiding half the numbers and brackets. The accent and pulse would remain the same and you'd keep the 4th pules.
2. The broken chords in b. 19 could be notated much better with a cross-staff tool. And to ditch the rests as well.
3. b. 8, 11, 12 with the rest and the triplet underneath. I would imagine that normally in that period and for notation reasons mostly, rather than much else you wouldn't have a rest, but the triplet would have for its first note the same as the layer/voice above. I think it'd look much clearer.
4. At some points they are quite tight. Perhaps reduce the staff size by 0,1 or 0,2?
5. Line up any dynamics that are missing each other (vertically), and make sure the dynamics are in the centre part of both staves, not too close in the one above, or the one bellow, unless you're referring to a specific voice in that place.
6. measure 10, right hand. The F there is a sharp (#) right? If so, since it's on a different octave (due to the 8va sign) it would be wise to show it again, in order to avoid any confusion.
7. Since you're adding slurs and some more specific dynamics in your part, why not do the same with Bachs part (the first two systems)? And what about staccato notes? None in the score (just checking)...
That's all I can see right now.
Nice job overall!
