Snake Sister of the White Soul

Xiao Qing / Green Snake the youngest sister
half cloth - no cloth - dress

Bai Su Zhen / White Snake the oldest sister
no cloth - dress - traditional cloth (not sure)

The name Bai Su Zhen and Xiao Qing aka the snake were based on the love story "Madam White Snake" or the movie "Green Snake." I drew it as my "White Soul" characters, and make them between the human and snake alike. I know Asian don't have blue eyes, but how can I make the difference between the White Soul (blue eyes, black hair and white body except head) and the Soulless (red eyes, white hair and black body except head).
