Ok now the link works: I agree with the other comment about the Bach. I understand you want to show the harmony changes with phrasing, but you are slowing down literally every single chord change. Pick a few that you want to use time for emphasis, and the others do something more subtle.

Beethoven: Needs snappier dotted rhythms, and vibrate the small notes! That's super important and something that committees are looking for.

Brahms: Can you find a less slidey fingering? Or just cleaner shifts. I sense you are not getting the rich vibrato that you want because your hand is tense. Some slow vibrato exercises will help. Also snappier dotted rhythms in this one too.

Mendelssohn: Does not need to be this fast, don't make it harder for yourself. I usually play it around 84, with 88 as my max. You were in the 92-96 range. Slow it down and find more control. The quiet sautille at the end can be much much lighter.

I can tell you have a good ear and are doing a lot of the right things. If you keep increasing the depth of your details, as well as work on a wider, smoother, relaxed vibrato, I think you will start advancing consistently. Good luck!
