Hi riga,
I like your playing a lot. Nice job!
If I had to make a couple of suggestions, I would go along with some of ganymed's comments. First, the three trills in question are not acciaccaturas (grace notes) or short appogiaturas, but rather full-fledged, long trills. Their purpose is to prolong sound (where the piano is a percussive instrument with a short tone decay time unlike a stringed or wind instrument). The two trills played in the RH in measures 7 and 30 have harmonic notes as accompaniment in the same hand--which is a good technique for all pianists to practice. So in 7, for example, you have to "layer" the sound. So the main theme now in the LH will be at f dynamic, the harmonic notes in the RH in the middle will be played mf, and the trill, which is strictly background sound only, will be even softer at mp or even p. It sounds challenging, and it is, but once you get the hang of it, you'll be able to play layered dynamics like this in any other piece where you face a similar situation--and there are many, many of them in the repertoire!
The other thing is that I would agree with is that there is probably too much staccato effect in your touch. While there is indeed some staccato and legato in Bach, most of his pieces are predominently played in what's called "nonlegato" touch, which is in between legato and staccato. That is, the notes are not closely connected, but are not short either. So in playing short slurs or phrases, for example, you'll simply want to gently lift the wrist and hand to taper it off, but without any short staccato effect. There are a few explicit staccato markings though, for instance, in the final measure. Thus, only execute that touch when specifically called upon to do so by Bach.
Your playing is very even and clean in articulation. In Bach, clarity is extremely important, so you're doing that really well. You also have a good rhythmic sense and your playing has very nice fluidity to it. I like it! Keep up the good work.
