Enneagram Character Types

I tried to visualize the 9 basic character types of the Enneagram personality test. They are out of order, but I'd be interested if others tried to identify them. The types are 1 (Reformer), 2 (Helper), 3 (Achiever), 4 (Individualist), 5 (Investigator), 6 (Loyalist), 7 (Enthusiast), 8 (Challenger), and 9 (Peacemaker).

Hint: If you're familiar with the Enneagram, you may know the three triads which group the character types: Heart, Head, and Instinct. The smaller dots on each visualization represent the respective triad.
