Saw many beautiful illustrations for these fairy tales done in classical Chinese style, but none of them showed fox spirits in the process of transformation. The fox fairies were either portrayed in fox form or in full human form. (Not counting modern animation/comic book fox fairy characters drawn as humans with fox ears and tails.) Thought it would be interesting to visualize a fox spirit in mid-metamorphosis and in contemporary garb.
The reference used is an Arctic Fox, which has a shorter muzzle than the red fox.
