Contemplating Purpose (Piano Solo)

This piano solo waltz was heavily inspired by the first Chopin piece I learned, Waltz in A minor.

It has the same style in the bass clef, and a similar order of melody sections: part A (8 measures), then a variation of part A. Then a part B totalling in 8 measures, except I didn't use a repeat. Then back to part A but with a key change in the second last measure. Then I had part C and part D totalling in 16 measures, unlike in the Chopin waltz, there is only a part C with a repeated 8 measure melody. Then finally the piece returns to the initial melody being part A plus a variation.
This is also the first piece I used the awesome new piano sample instrument on flat. It's a new feature. It works perfectly for mellow piano solos or waltzes. I actually changed some of my old piano solos to use it, so go check them out to hear what they sound like now.
I hope you enjoy this piece!
And I challenge you to come up with a waltz in the same style and format as the Chopin waltz in A minor! (If you want to.)
