It worked pretty well though I'd have changed the chords for the bass so it played something consistent and from within the C chord but slightly different.
With a single chord son usually the tempo is dynamic to retain interest or the the levels change. For an hypnotic effect the texture is often developed.
I think you've created a great bed to experiment even further with.
Nice job.
