I supposed to quickly make "exoskeleton" for a boy. Inspiration came from movies like Ironman, Transformers or Halo game. 

 

It was literally speedsculpt. I made him in about 9 hours. All modeling took place in ZBrush and then I rendered whole model with different material applied in MODO. The rest of work was made in Photoshop, that means separating materials, dirts, scratches etc.
