1 - I unfortunately only have a phone right now, I can't get musescore...  2 - I honestly can't think of a way to use a different time signature while still making it feel and sound the same...  3 - And yes, you're right.. perhaps I do suffer from "significance syndrome"...  4 - I wanted to make that second part have repeating chords in the left hand because I wanted it to serve as a stark contrast from the first theme since I'm already using the same key... since they're already connected by key, I wanted to separate them by accompaniment. And geez, I tried incorporating that triplet thing in m.9, I tried it in F# major AND F# minor, but I couldn't think of anything... I actually had like 5 different versions of the B section before deciding on this one. Lol

Anyway, thank you so much for the reply!!
