Nice piece. It's the kind of work I listen to from time to time when I think mesmerising is going to relax me. The motif repeats itself continually aside from a break at about 1'18", with variations in the instruments either side of the piano. It comes over as "minimalist" (like Philip Glass or Mike Nyman), a well-established genre.
In fact if I may be so bold to suggest looking up a track on "Glass - Organ works." track 5: Satyagraha.
(The chunk on Amazon does it no justice) and while melodically very different from your work evolves in a similar way, almost 10 minutes of it.
Well done.
