Using several light sources is tricky. When using 3 you need to pay attention to where they're supposed to hit on your render. His right arm - the one behind his back, behind his left arm - should have red light reflecting on it instead of blue light; the blue light reflect should be no the bottom side o reflect the right-side blue light source - since It's positioned behind his body, and not infront of it. Meaning instead of being blue=top and dark=bottom, it should be red=top and blue=bottom - again, this is his right arm, the one behind his left arm, the far away one. Or you could replace the right side blue light with the left side red light and everything i fixed - since the render's natural blue light will be dealt with.
