Fun straight forward build. Pretty straight forward and absolutely loved final result. The final product being able to make merry go round move makes it even better. Just a very nice set and build.
Good build over all, a little repetitive. I'd recommend adding your minifigs to the carriages before you put the carriages between the wheels. Also a minor nitpick, the light blue accents and translucent yellow studs on the face of the wheel aren't on both sides, so it looks a little bare from the back.
