wow. this could have been great. cute subject, something with controllable motion, interesting angle. you should have worked at it a bit more, from slightly different angles and with slightly slower shutter speeds. as is, the tip of the shoe being in focus says you were on the right track, but not quite getting there.
Pretty good attempt at a difficult challenge. Would be better level rather than odd angle, and if subject were sharper, try matching the motion more exactly.
