I like this on several different levels. First, it's beautiful and the black background gives it a lot of impact. Next is the contrast between the formal, staid vase with its classic form and the frenetic spinning pinwheel; a child's toy juxtaposed with something children are generally forbidden to touch. But the pinwheel isn't really spinning; this is a still photo and any sense of spinning is pure illusion. Which leads to the next level: the still image of the pinwheel looks a lot like what is normally placed in a vase: a flower. It isn't alive, yet the sense of spinning makes it "lively", and the green color is a symbol of life. Of course, a photo of a real flower isn't any more "real" than this photo is; photos are just pixels on a screen or ink on paper. So there's some depth of meaning behind this simple photo. I have no idea whether you were thinking of all this when you made the photo, but that's the beauty of art: it doesn't really matter.
Good composition here; very simple and nicely balanced. And good use of color. Great focus and processing. Sharpness in particular is just right.
A couple of things I don't like: The glare on the pinwheel is overwhelming. Difficult to avoid, certainly, but still distracting. And while I really like the light shape reflected in the vase that helps define its form, I really wish it went all the way to the edge of the vase. Stopping so close to the edge kind of makes the vase look translucent right there. That or it was shaking during the exposure. I know it wasn't, but that illusion doesn't really fit with the rest of the photo.
Overall, an outstanding photo. I've really enjoyed studying it.
Love the greens against the black, and the fact that the spin is obvious without being lost in a complete blur. I wonder if you'll catch flak for the light on the vase? It seems like an error but I've grown to like it.
I like this - it's just a simple, but unique composition. Isolating the pinwheel in a studio shot is a good move, IMO - no distracting background, and the choice of colors are attractive
