In my opinion there is just nothing 'striking' about this photo. It looks like a quick snapshot. It is a good idea but the composition is just not there.
Whoa - couple things here. First, no real motion - it's a pretty static picture, frozen in place. Second, what's up with the halos around the person and parasail? Either it's been dodged to lighten it up or the unsharp mask way overused. Now I see that it's been validated, so it's not dodging - not sure where the halo is coming from...
I'm sure most will say it but it's too blue and you can see where the work you did to dodge the shute and person is way over done causing a "Halo" effect
This is not good. Yes it is action but no it is not a good photograph more like an over worked snapshot. Whatever you did to this image was too much. There is too much noise maybe caused by using shadow/highlight and it leaves a glow around the guy in the air.
You get an (A) for effort but remember less is more. As a good photographer once told me when you think you have adjusted it enough back up about half.
Got some halo going on around the chute and 'flyer' in the air...sky looks weird to me and cropped a little to close at the top...but it certainly meets the challenge.
