Intro: Indeed a slower tempo than usual, but it gives a feeling of more freedom and liberty. The 'retenu' is too exaggerated though, in my opinion.
At 'un peu en dehors', the tempo seems to be dragging at that point. I am not sure if it is just the recordings, but I think the crescendos and diminuendos could be slightly more exaggerated.
At 'un peu cede, molto rubato', I love what you did there. It somewhat complements the free feeling you established in the beginning. After that, where it is 'a Tempo', again it is a bit on the slow side. The notes don't seem to be even either.
At 'Plus anime', I just don't feel the anime, nor the gradual crescendo. The pp subito part is good though. I like that crescendo towards the repeated chords.
At 'un peu cede' to the end, the poor recording quality really blurred things. I cannot give a fair remark to that.
Just a few random comments and opinions. This is quite a unique interpretation, and overall very well done. I look forward to your new recording.
