Looking pretty good so far :).
I don't know if design is that important (since you're focusing more on animation) but in games like final fantasy and kingdom hearts you will notice a lot of little accecories and details on every character's clothing.
So what you could do is find some refrance and add some more details yourself if that's something you're interested in.
As for the poses and anatomy everything is looking pretty good. Get some referance for the hands and you're gold :).
