It bothers me that the ball is just barely in the photo... I'm wondering if you cropped it this way on purpose or whether thats just how the shot was. I think you could have taken a lot more shots to get that better. I wish the club were already coming down rather than just up on his shoulder, giving the viewer more of a clue about what was going to happen. I think you might have been able to fix a little of the white sky by using a polzarizing filter, but I'm not sure.
Hope he missed the camera...:) the contrast and saturation on this shot needed to be played with a bit. and I would have liked to see the ball a little distance from the edge of the picture. 6
Having the ball right on the edge of the frame, and the subject centered doesn't help this shot at all. Had you panned to the left, so that the club was 'pointing' into the corner of the frame you would have a much better composition IMO.
Apart from this, and the skin tones looking a little too red, the shot isn't that bad and certainly meets the challenge.
maybe this could have been framed with the ball more in the frame, rather than so tight up against the edge ? The background seems really dark - mainly because of the sky that has crept in at the top. You may have gotten a better result if you'd framed it without the sky in the frame at all ?
For what it's worth, the boys left foot should be flat on teh floor. he is young enough to be supple enough to do that and it will imporve his game no end, and stop him topping the ball. The right arm shoudl eb tucked in a bit more, he is chicken winging a bit.
Great shoudler turn though! Wish I had started thsi young ;)
