I think this is a very good photograph. She has very sure stature and distracting stare, an aspect of maddness is slightly displayed in her eyes. She is fanatic of what she believes and is ready defend it - she already has (bloody knife) and has crossed the line. She is looking forwards and not caring what happens behind her.
Three dimensionality is strongly present and well set up. The cross, her figure and background fit in together and create a sense of depth. Lighting is great and she poses with certainity - her pose does not seem unnatural.
Very fascinating photo !! This model have a great personality and you show it very good. I like all of composition, colors -- this adds atmosphere of fear, lostnes, surreal.. Anyway GREAT photography.
