It seems to be a dragon made of fire. Totally. That's why some flames escape around the powerful creature : dancing inside the air, dancing some instants and disapear after the danse in the universe. Black and red. For me, your choice of the colours are the best. For lots of humans, the red symbolises the blood. And so, blood is life, the power's life. Maybe the dragon offers life to the universe by its breathing.
A lukewarm breathing. Perserving us of the frozzen ideas.
