First the face of the girl in red (ish) and the details in her face, her nose, her smile, the shape of her cheeks, her eyelashes, she is engaging lit and shot. Then the light on her chests drew me to what she is holding, you use light to create a wonderful path for the eyes to follow, starting with a moment lingering on the first girls face. The bright white fan really stands out, but the light draws me onto the middle girl, her face and headdress really draw the eye, i then took in the right (her right) of the last girl's face, and straight into what she (and they all) are looking at. I didn't notice her horns right away, or that the middle girl was also holding something, the composition throws the 'real' elements of the cosplay into focus, their faces stand out so well. Hopefully that is a vaguely useful answer to your question ;)
