try harder.
you seriously need to put more effort into your renders.
if it doesn't take more than 10 minutes to render, it's not worth rendering imo.
I can see you are making an attempt at GI, take out the light. then in render settings activate Global Illumination.
as a final note, the pose looks a bit stiff, try rotating his chest, bending his knees, and moving his feet out a bit.
