There is so much to love about this image, the flowers against the grungy background and the lens flair that suggest flowers in the blurry bucket. One I can look at for ages.
I love the textures and neutral colors in this image. The lens flares create an exciting sparkle while the background looks like an oil painting. I haven't any idea what he was doing in 1/6 second to create that much blur, but it works for me. Normally I wouldn't like the horizontal barrier the flowers create, but in this case, the white of the flowers balances the bucket, the lens flares, the blur, and the vertical lines of the wall. All together this image, which shouldn't work does work as art. IMHO
A little bizarre, yet interesting. :-) I like the captured motion. The exposure ran just a little long and has blown some highlights (particularly the flowers). The sun flare adds a little wonder, like "what the heck is it?", at first glance. You'll certainly be slowing some viewers down to check this out - hopefully! Good luck.
