You have embarked on a most demanding Brazilian piece and have so far made a good start.
I hope I'm not being too bold to say that your beat needs some more work. I feel I can say this because I have also been working of this piece for some time now and I still cannot play it at the tempo you are attempting here (I'm getting close, though
To achieve that, I have been working on it with a metronome at a slow tempo to make sure that I can not only hit all the right notes, but that I also can keep the beat going non stop, including the fast scales.
With a 2/4 beat, you are playing it at around 100bpm. You could set it at 60bpm and focus on accuracy first. When you feel comfortable at 60, go up a notch or two and start again, always making sure you don't lose the beat. I think this approach will bring you up to the next level on that wonderful piece.
I hope this helps. All the best to you.
I enjoy your great recordings of early music.
