This is a technically perfect artwork. The form of the circle is impressive as well as the skull of the wolf. The colors are very well chosen, emphasizing at the same time all the details of the skull by using a dark and strong contour in all the head until the teeth. The red circle is reminding obviously the National flag of Japan. The author has probably been inspired by traditional Japanese ink prints. The dark composition reminds also European symbolism and Contemporary Gothic patterns but above all the artist had developped with talent his own style. The using of a stylized floral frame reinforces the creepy esthetic of the drawing. Beautiful!
