oh what fun rob, did you go in one? (i say what fun, but i wouldnt go up in one if you paid me!), but they make cool things to photograph thats for sure! love the colours, looks busy there too!
Way to dark and the balloon in the back kinda spoils the symetry due to it being at a slight angle. The pic needs a wider angle anyway though (possibly in portrait). Looks like a good quality picture, equipment wise.
