tbh one pet peeve I always have about animated characters is that their bodies don't move aside from the parts that are needed like the hands in this case.
I think it's better if the character's body has some sort of movement, even if it's small. Or make do it like what this cloud is doing (I don't know how to describe it):
It's static, but there's some sense of movement in the cloud if you know what I'm talking about.
Or disregard everything I said since what am I to say about other people's work when I barely have any experience in animation.
