Not bad, but the shading and anatomy need work. Plum's lower half seem too big for her body, in both lengh and width. Her hair is shaded oddly too, in a way that makes the hair seem too solid and shiny. Like plastic-y, Iguess. Again, not too bad though. You did a great job with the color choice and made a great and interesting pose for Plum.
Also Bravest Warriors fuckyeah!
