Cant decide if Im missing something here, but I just dont like it. Composition is OK, but the subject has nothing to do with speed, and its too bright. I like the feeling of dissonnace here.
Well there is not much speed in this picture just a blurry horse shakin his head And its all too blurry And the fence is disturbing. Anyway Good luck :)
Can't quite see what it is; a swinging horse head? I think there's too much light in the upper section. And either the horse or the fence has to be sharp in my opinion.
