The Costume is splendid, and the shot is great for showing it off. But it just doesn't match the effect.
The subject is looking off in the distance and there is just a lightning bolt hitting the ground for no apparently reason. The stance is very neutral and there is no implied motion. An ambient aura or multiple lightning strikes around the subject would fit the pose better. But as is there is a lack of focus for the effect.
I hope my observations help in future endeavors they are not meant to be mean spirited, keep up the fantastic work
