"Asari from Mass Effect as well as, like mentioned below, the Twi'leks.." -worth mentioning again! With your well defined facial structres and details it would be wonderful to see more original concepts!!
I like the fact that the stripes and spots fade away, it reminded me of a fawn, and we they grow older to the doe or buck they lose their spots. Wonderful and beautiful concept art. So they decide on tattoos when their spots go away?
