Challenge: 10 definetly means the challenge
Composition: 10 fills the frame just off centered

I really like the composition here. The model seems comfortable with the camera, almost letting you view through him if that makes any sense. The only minor thing I would change is the brightspot on his right cheek. Maybe if you rotated position just a bit to the left and had his face follow, that would've solved that. Good job!
