Pinwheels are a tough subject since the colors all blend (depending, of course, on the rate of spin and the length of exposure.) I did one of these as well back in 2012 and was pretty disappointed with my results. (It won't shock you to learn I did it as a black and white. ROFL)
Anyway, looking at your photo, it can make a very interesting abstract, especially with the pattern of the shadow. (It would also make an interesting black and white. .)
