My son a year or so ago was into urban ninja and he spent most of his time jumping around of of things, really irritating when all you want to do is shop :)
I got this great image of him freestyle jumping by getting down low on a flat landscape, it makes him look like he is jumping really high, when in fact it’s just a few inches of the floor.
The back drop of the sky was really important for this picture giving the impression of height.
