Interesting work, very well structured despite the short length of the movements... It Is a quite manneristic Composition to my ears, the First movement recalling vaguely the style of Prokofiev, the second One a bit of french modern School, the final a touch of Kabalewski....but It Is pleasant as a whole, and It Works well even as a non-didactic piece, bravo Luis, refined interpretation in every detail!
I'd glad you enjoyed it! Sure it sounds French, and I hadn't linked the tonal liberty with Prokofiev, but you're right! It's modern beyond pedagogical intentions, for sure. This is his most interesting sonatina, in my opinion.
