I see no movement in this piece. Shes just standing there just like the definition of a statue. Wouldn't you want a statue that shows some sort of movement?
The legs in this particular statue looks stiff, compare to the one they have sitting on a Sphinx. See the difference between the 2 especially the legs?
I'm not sure if these 2 statues are from the same artist.
I love the one sitting. Something about it has a natural movement or feel to it.
I know they are two different characters, but just my observation and opinion with movement.
