Just dropped off the face of the earth for a few days for midterms..... but generally speaking were I to audition with this piece I would play it however I thought it should be played. While I will hopefully have grown in the coming years, I see no point in modifying my playing in an audition because if I have to do that to get in, I'll have to struggle with it for the entirety of my time at that school. If a school would reject me for not playing within a specific paradigm for a piece then one of two things is happening. Either the school is not a good fit for me or I'm not at a level to pursue music in such a way, and in either case, it's probably for the best that I don't go to that school.
The music of Bach, and modern practices in keyboard playing are worlds apart. For one, it was not written for the modern piano; and another, practices have changed in music notation and performing.
It is more than likely that you started your musical journey with the music of some late more recent composer, full of 'emotion' and expression, expressing all over the place. Likely the music had a title, and some intricate backstory as to why it was name this way. I know this is speculatory, and most probably not true, however, we cannot forget we live in a post-beethoven, post-brahmes, post-rachmaninoff, post-scheonberg, post-cage, curently-einaudi/yiruma world.
In terms of cannon, your perception of what make a apiece of music by Bach, Bach's, will forever be tainted in the practices of modern keyboard playing, making it by default a world apart from Bach. That is the true hurdle for playing music from over 300-400 years ago.
It is likely there is nothing wrong with your interpretation of Bach. It is most likely a very nice rendition, however, when looking at music study at undergraduate, graduate, and post-graduate levels, there needs to be at least some authority and maturity. Angela Hewitt learnt all 48 preludes and fugues from WTC; she then relearned them all because she deemed interpretation was not sufficiently 'authoritative' or 'authentic' for recording.
It comes down to, who are you playing for:
Yourself and pleasant sounds?
The music, and what Bach wants?
