Hello Luis! This is a nice/pleasant sounding and well developed piece! It seems to me it went as A A B A C C B A, with three melodies, a consistent but amusing left hand part, and a satisfying flow of events.
Your A section has a simple, but complimenting, 8 bar melody that I think goes well with the harmony! The second time the melody comes around, I love the second piano's accompaniment! It really adds to what's been established already (the 16ths are so goood). The B section is a bit busy, but it's a really beautiful contrast to the A sections, and lemme just say that bars 27 to 33 certainly grew me! I like the octaves and louder dynamic introduced here. Of course, the return to A is satisfying and reinforcing of it's melody. And now we get to the C section, which I LOVE the change in texture and dynamic, which really offsets it from the rest of the piece and stands out to me pretty well. The second C section is pretty warm and heartfelt compared to the first C section, which came off has a bit cool. Two nice textures to relatively the same melody. And with that the return to B and then finally A makes for more reinforcement and more enjoyment out of this fine piece!
Great job!
