Crit for Visual Mapping

the feedback from this crit seemed to echo what I had thought about the work myself, there were good elements, but it was not composed very well. The image seems imbalanced I think, so I am going to create another illustration to go in the bottom right as this area is comparatively bare. Then I will probably go down the route of dividing it into a triptych which will make the image less busy and chaotic as well as helping to communicate the differences between each area of London, something which I intended to be one of the main features of the piece.
