I have played this...
First of all I should note, to those who do not know this, this is half the piece. There's the middle part missing. But this makes sense, as Jolteon says if they had a couple of days to study it.
That said here's my harsh feedback:
It's a very tiny bit unsteady (again this makes sense), and the dynamics seem a bit 'uninspired', like you weren't exactly sure what to do.
But the most important thing that I felt missing was a more 'real' Brazilian feeling! It was too "classical" in a sense. Too "straight forward". Too "normal". And it goes against Milhoud somehow... :-/ And let me explain a bit further: I don't remember the score outright, but I seem to recall that it didn't have any accents, but the accents are strongly needed. Especially in piano 2 (Not Joelton) who's playing that pattern. It takes more a kind of 'mambo', or accent, or a hic up ideal to make the rhythm happen. And even the left hand of Joelton is not enough to bring the 'joy' futher in the piece.
Despite of the above, I'm pretty sure that at this point I'd need 8 hours for 2 days to make a piece like this happen, even if I've already study it. That alone speaks for the quality of you as pianists! So take the above with tons of salt and feel better that I'm being harsh with you: I'm half jealous, half expecting excellence from both!
