Not sure you had to add the copyright information and unapproved circulation to these images. The backgrounds really are just a little too sharp, especially on the last one. I know being in the right position is really important for jumping, straight on being that position, but you may have been restricted in where you could be. The first frame the fence in the background doesn't look real, was it photoshopped? However the first one is pretty good. Second one, horizon line on the fence is crooked, just a little straighten would fix that. The last image just has way too much going on in the background, a tighter crop would take some of it out and help.
