I like it, the piece has a dreamy mood (in my opinion).
I't is not so powerful and strong like a first movement.
So it could be a 2nd movement, even if there is a sonata form.
I think it's good to have people experimenting with old rules. :)
What I like most in the piece is, that you made the piece interesting
all the time. Some (especially classical) 2nd movements have the problem,
that they are getting boring after listening a while.
So, good work! :D
