Flags combine to form an inspirational image.

Solution

I liked the way the flags appeared to easily lock together through the shared colour red and then resist separation (in a design sense). This union suggests some type of mechanism of two interdependent parts, each of equal importance to the function of the whole. Additionally, the bridge of red between the two flags may be seen as the flow of creative energy between the two countries as well as peoples, either as tourism or immigration/ emigration. Or it might just be a night time cityscape!
