The wolf in this piece is highly detailed and gorgeous. The shading is wonderful and the detail and hard work put into this piece is marvelous. I would suggest that you create the middle section of the wolf a little less human and a little more wolf to make the piece pop a little bit more. For the tail, as wonderful and luscious as it is, the purple just seems to stop midway. If you shaded the fur to create a fading illusion, the tail would flow better and the piece would become truly wondrous.
Thank you for your time and talents.
