Bach played on harpsichord, so he couldn't use dynamics, so Bach used a lot of articulation, that's something I miss a bit in your video. Everything is legato, you can phrase it more, get your hand a bit from the keyboard after playing the theme. This will improve making it sound like a two-handed invention.
Try to listen to each hand, so that you can hear the theme in each hand. Now I mainly hear the right hand. If you hear it yourself, we can hear it too, which will greatly improve everything.
And personally I wouldn't use legato on the 8th notes, but the thing what's between legato and staccato (forgot the word) .
The things that were really good were your dynamics, and the clearity, so keep it that way
