as art, it is what it is, and i like it. as a challenge entry, you were stuck with the 1/25 catching the movement, but losing the bird (and i really doubt you could coerce/coax the bird...).
I like the Silhouette. I think the out of focus and stray bit on the right take away from the impact. This makes me think of a nursery rather than wind.
there's only one person on this site capable of a shot such as this...well, there are a few daring enough to try, but only one who can actually deliver, as well as have the guts to put it out there! great image!
i know spot editing isn't allowed in these basic challenges, but i feel like the shadow on the right distracts slightly (although i think that leaving it there with this crop is more effective than if you had cropped it tighter) - really like the idea and use of shadows.
