Austenite,
I found the Sonata you posted in October 2018 by searching for ideas to embark into composing the first movement of a symphony. It is great, with fantastic bits of inspiration. The first and second movements have a great "Latin" early XX century flavor. The first one reminds me of the 2/2 Venezuelan "Joropos". The second one has that great Tango flavor that evolves without losing its flavor, and it seems to be calling for a wilder development to break molds. The third one reminds me of a Mazurka, and it is quite contrasting. My favorites are 3 and 1. 3 has so much potential for orchestration, I can almost hear already a very interesting series of alternating sections growing into "tuttis". ¡Pura Vida!
