That opening is so familiar. I guess it's from Chopin waltz no.2!
Really chopinistic composition here! The melody, modulations,ornaments, expression, style, everything. Really good job to pay homage to Chopin.
The modulation to E major in the middle section in 2:33 comes from Chopin's Polonaise in the same key? Oh I am wrong!! it's in C sharp minor!! Really showy passage here and after. Some elements from Chopin's mazurka also appears here though not in triple meter. Good job here! Love it.
I think it's fine to end here by repetition of the A theme, as many Chopin's smaller scaled piano works also end in this way. But adding a coda will also be fine. It really depends on how you perceive the piece.
Overall a really nice piece! My only complaint: Really want you to post your previous 51 pieces here too! Also this post is 1 year before. Do you have any new compositions? Really would like to check that out too! Great job!
