The way the light hits through the petals is extremely pretty. Easily brings out the color in the flower as well. The direction the flower is facing is the same direction from where the light is coming from. This kind of lighting gives a dramatic flair to the overall photo, thanks to stark contrast between the light areas and dark shadows.
Agreed. the light through the petal is gorgeous. The extreme close up and parallel alignment of the flower with the rectangle is interesting as well.
