There's a good sense of anticipation here, but it's odd that you've chosen to conceal the very subjects of the challenge theme! Weirdly, I just can't find much to say about this other than I feel that it's a bit lacking in interest. I would have given space for more of the player in your composition though as the crop does look stifling.
I'd have cropped a bit more, especially at the bottom - I think the large amount of blurred grass distracts from the action of the kick. Otherwise, very good!
Good idea, but I think this would have been better with all of the right foot in the frame also and then I would have cropped away half of the blurred foreground, yes, panorama version with all of the right foot would have been great.
This is dynamic - a good captured moment of action and a daring composition. I wish the legs and feet came just a bit more into the frame - but I like all the open green space it works well with the sense of action and movement - keeps the viewer in mind of what the next moment willl bring. 7
