How does a painting give the impression of power?

I think that a painting gives a impression of power because it cost's alot of money to get your painting done and how your posture is and they way you look can tell people is your powerful or not.

For example Queen Anne's painting look gentle and soft and not powerful but Queen Elizabeth 1st painting look powerful. Sometimes its also about what they wear in the painting because for like Queen Elizabeth in her paintings she wears alot of jewellery (real gold) that also make her look powerful :)
