I think these Colourscape things are great (I went in one in 1984 in London). It's a shame it didn't do so well in this Challenge - maybe if your model had been leaping across to show more motion...
Interesting scene here. I do not however get the feeling of a jump going on in the shot. The motion blur doesn't appear very visible to me, and plays a minor role. I really like the colors but I think that maybe something is lacking in the composition of this photo.
