I am working on a project that involves shopping mall maps. I have started with a DWG AutoCAD file and worked it in Illustrator to get a simplified mall map but I am unsure of how to advance the look. The maps are to be used in conjunction with a routing engine to show shoppers to to get from Point A to B. Since the application is all visual and highly interactive, the map design is critical but no matter how I work it, I can't seem to ever get comfortable with the look and feel. I was hope to get some critiques on what I have built thus far.
This map has been simplified to eliminate the subdivisions of the retail stores as the router handles the names, logos, artwork but that can be added back. I am mainly concerned with the colour scheme and background and how I can enhance the look (eg possibly adding the parking lot in with it).
