I agree with Kurt. The legs in the concept drawing look more to scale with her upper body. From the concept drawing, it appears with her arms to the side, her hands are almost to the first knee joint. In the model they will go just past her hips.
I also like the toe pads in the original concept drawing.
Great job thus far. I love the bunny ears. The paint job is also very nice!
