Nan Desu Kon '09 had a Greek astrology theme and I did 13 images for them. I tried to stick with the associated colors and gems, but mostly had fun with them
Also, the streaked hair is part of the NDK mascot design. Females have black hair with a white streak, and males with white hair and a black streak. In this case I went with dark hair rather than black.
This one was used as the main badge if you pre-regged, so the format is a little different from the others.
