.: Sailor Saturn . Beginning of the End :.

Presentation: . A darker background would enhance your lighting effects better. Remember, the idea is to bring attention to the subject of the photo. Your background is a bit distracting. These are more choices of the photographer and I realize that sometimes you have to go with whatever you have.
The low angel works extremely well when you want to add her power as a counterpoint to her beauty. Low angle shots tend to make characters look more menacing or powerful. The photographer takes the place of the audience as being in a submissive position.

Character:
She's an incredibly powerful character, yet that seems to be somewhat lost.
Expression and emotion of the character are spot on.
The pose is good, except you may want to reposition your arms and right shoulder so that your head and face are more visible
Excellent cosplay and good photo.
