One thing that struck me several times during my week at Soul Survivor, was an angelic looking shape formed by the meeting of some of the seams in the Big Top. It struck me as an image of blessing although it comes out a bit too dark and menacing in this watersoluble graphite sketch.
Perhaps inverting the colours would help? A quick experiment suggests it just looks like a scary drawing done in chalk on a blackboard. As a picture, it is quite interesting but I think it fails to communicate the sense of being watched over benevolently which I had in mind.
