DD Head Varieties Venn Diagram

I love studying patterns and how they can relate to each other. I've been noticing more how certain DD headmolds seem to belong to "families", varying to yin and yang. "Moe" being the yin, and the yang being "Angular". 

Delicate are headmolds who seem to be very feminine, and realistic are heads that seem almost human-like.
