I can't play this piece, and I've never tried. So, I can't speak to the nuances of how it should be played, or proper execution, etc. But, I will say, from a listener's point of view, it's more than just fine. Your interpretation has many facets. And I think that can be, and in this case, is a good thing. Unless, you want to play it differently, or better, or are still figuring out how you want it to sound. I sometimes suffer from "REC button syndrome"; play something fine a hundred times, then, when I want to record it, well.... it doesn't come out right.
I once heard an interview with Andre Previn. And he said some of the things he liked about playing solo piano, as opposed to being with a rhythm section, even a trio, was that he had complete freedom to alter the tempo, the dynamics, even the melody, on the fly, however he wanted. So, you're in good company.
