I love how detailed it is, I suggest if you want to further improve is to learn how to loosen your poses and any small things like clothing wrinkles, facial expressions, small details such as tone in the body (not that you don't already have an understanding of it). if you plan to color it, make sure to add shadow and depth so that it doesn't come off as too busy and messy. I'd say this is a solid 8.75.
Jean-Auguste-Dominique Ingres was a French neoclassical
painter and the acknowledged leader of the neoclassical school in France. He
was a talented painter and draftsman known for his smooth textures in paintings
and drawings. The texture was so smooth that even appeared to be illusionistic.
