Sorry for not have answered earlier, so much things to do....
I was not speaking about one particular piece, but was listening to all of them. Something let me feel nervous a little bit, listening to your music, and I started to wonder what it was. I finally excluded sound issues, because that´s just a question of personal taste and equipment (and money) available. I actually first thought that it might be the release of the sustain pedal, that your DP upon releasing it cuts the sound so sharp that it produces a sound gap, as if your flow of playing would become interrupted. This still might be a present impact to hear in the recordings. But it to me then also appears, as if your timing would alter throughout a song, and that subtle interruptions might be introduced by your moves. I am wondering, if the release of the pedal with your foot might delay your playing in a subtle way, like a tiny multitasking issue? If I would have observed this correctly, then playing with a metronome should make you feel uncomfortable, and therefore I suggest to try it in order to find where the gaps result from.
But please, don´t rely only on my comment. I am still a beginner and maybe some more experienced members around or even some teachers around might tell you the complete contrary!
