Two movement piano piece in D Major

Any and all feedback is greatly appreciated.

Please note that some of the grace notes are written like they are due to a better playback performance.

Any advice on what the genre is? When it was just the first piece it was a Bagatelle, but now I’m not sure

This is bright and fresh throughout, and plenty imaginative.  If you ask me, this feels like a Sonatina.  

In the first movement, you give the oom-pa-pa a break just in time before it get gets monotonous - even Viennese waltzes break this rhythmic figure occasionally. 

I'm guessing that staying close to the tonic key is part of your style, but I think both movements could use more modulation to other keys in the course of the piece to freshen to tonal palate.  Also, the first chord in the left hand of the very last measure is strange to me...consider making it an octave D instead of A.  It will solidify the finality of the ending.  

Good job!
