The texture, toning and shading are very good. All these differing textures are not easy to realistically reproduce, and they look great. I can see skin, hair, fabric, amrour, leather, denim... and the tattoos look great.
Technical stuff aside, I love her design. I love her hair, her unique face. She's got lots of character in there. She's casually cool, and yet exciting. Overall, great job. Does she have a name?
