Thank you for your analysis Margaret, it may seem odd to you that I keep adding lighter parts to these images and have not been adopting the excellent advice. I definitely can see in this image the opportunity to introduce a mirror image of the black-and-white of the right-hand corner. A great enhancement. This is in fact a large balloon like object as part of the Illuminate Adelaide display but with extreme ICM providing the three-dimensional ridge like patterns in the foreground.

An interesting stroke around the image. As I said in your previous image the eye goes to the lightest part and also to what is most colourful so the white section top left distracts and needs to be darkened. There are strong shapes in the foreground leading to more curvy shapes in middle and background, the latter giving a sense of movement. Weird - I can't imagine what it is.
