It's a nice piece, but i'm not sure what you're going at as mentioned above. Here's some things I would do. And what software are you using? I'm curious to what boundries you're working with.
- The trill at the first part sounds a bit too on beat. (this is probably just a software hold back) It would sound a bit more natural if it were ea fast triplet of some sort.
- Wonderful entrance, but at about 3 seconds, there's an akwars key/tempo change that confused me for a second. I'd hold the the high note for a bit longer before continuing on. (Again, it might just be the software)
- I love the part with the left hand 16th notes. Suggestion: make them stacatto for a more Baroque feel.
- The last chord doesn't sound right. If this is a first movement, I can see it leading in to another song. If not, the last note could be brought up to the tonic.
Other than those little things, it's a nice peice. Very Motzart feel to it.
