Here's my revised version.
I've altered the melody aswell somewhat, keeping the same basic pitches though. The harmony is still simple, all diatonic, etc, but using more than just tonic and dominant this time
I think a dance movement (maybe a three voice Minuet or Bourree for keyboard of something?) sounds like a good idea
Maybe later we could try something more complex, but for now I think the simpler the form the more we can focus on the harmony
