This is a map showing the concentrations of different ethnicities living in London. Red represents white population, blue represents black population, hispanic is orange and green represents the Asian population. There is a great fill throughout the map as well as a great use of colors, but I still see two issues. First, the orange and red dots blend together a bit too much. Since the white population is so large, the orange dots get washed out. Second, the Asian population is larger than is depicted on the map. It may be the color or how closely the dots are placed,  but the Asian population is a bit more dense in population than is shown.
