My tip for you would be to try to push the sillouett of her. You have all of these interesting asian-inspired elements, right? And I thin if you moved them out from her body more, it could really make her look coolel.
Like, exaggerate out the shoulder rope more, make the back knot protrude more and a bit bigger.
You haven't started to add anything the the feet yet, but I definately think you could add some cool protrusions over there as well to make the sillouett even cooler. Just edges and bulges and curves just to make the sillouett stand out. ^^
Hope that helps.
