That is a magnificent sketchcard version of Amaterasu by Melike Acar.  It is part of the upcoming Classic Mythology set by Perna Studios and it uncovers the deep source material of a modern pop culture hero.  Video gamers know Amaterasu in a quite different form.

Capcom created something called Okami in 2006 and it may be the most beautiful video game ever made.  The main character is a she-wolf who incarnated the spirit of Amatersu, who is a Sun Goddess from the Shinto mythology of Japan.  The Okami character was so popular that she was also included in the Marvel vs. Capcom 3 series.

And now, with a delicious wink at John Talbain from Darkstalkers, Amaterasu is getting a new hilariously hairy alternate costume.

Mad coolness incarnate!
