Here are just my sketches on the Juri by Hex. I shrunk the head and thinned the back just a bit. I also fixed her chin, made the right eye smaller and evened out her hair to fit the head better. Another suggestion would be to just straighten out her left arm and have it more relaxed to her side.
Remember, when do a 3/4 view of the face, try to keep the objects further away the same size or a little smaller.
