Diabelli Project 013 - 2-part Invention

The Diabelli Project is about offering my weekly flash-composition sketches freely to all. Like Antonio Diabelli's theme these sketches aren't great music. But perhaps (as in Diabelli's case) there's a Beethoven out there who can do great things with them.

This entry's pretty simple -- although there are some parts of it I like. The opening motive outlines the basic tonality, and the second voice continues the downward motion, liking the two. (click to enlarge)

Where does it go next? I'm thinking there should be more downward motion throughout the piece, and that dotted rhythm should turn in on itself about halfway through. But you may have different ideas.
