Hi Marsha,
I like that you are doing this for a friend, 9 characters, phew that is hard.
I agree that you already got better on your second character.
Maybe you can try some poses that are a bit more dynamic,
so there is a bit more movement/action in the pose.
Your second character's feet don't feel as grounded as the ones
of your first character. You have chosen a though job but I think
you're of to a good start.
Good luck
