Piece in Bb Major

I'm not sure what this piece is (is it a rondo?). It is based off of a theme I thought of last year. Probably a fair bit could be improved. Any ideas? Thanks.

I would exactly call this a rondo (strikes me as a type of variation with a consistent harmonic progression repeating, like a passacaglia sort-of); though one thing I love doing with my works is printing them out and annotating it, marking important figures and motifs, the structure, the major sections, etc. Give that a try! The piece is very calm and absolutely has an intuitive, improvisational quality; you build nice drama, though I could see some areas where you could go even further, perhaps by changing register or reducing the texture or something like that. Good job!
