The concept is nice along with the colors of the foreground images. However, the background is too blurred and the color is too desaturated for the foreground image. The red font looks a little too plain for that signature. The lightning effect looks too jittery and takes away attention from the girl as it travels across the picture. I think adding a gradient map can simplify the color scheme in that picture without adding too much distortion to the darker areas because I think the background's colors don't match the foreground image.
Based off the sketch alone, the point of gravity looks very distorted. The girl's head is bent, but her hair is still upright, unless that's really strong gel or if the image is actually at a different angle. By the way, if it is in a different angle, the shirt extends too far outwards on the shoulders. If not, her shirt looks very tight on her breast, but it's loose everywhere else. It looks very nice though along the face and the body pose looks very unique
