The right side of Corlack's face is ruined, presumably from being smashed by some brutal melee weapon. Standing as straight as he can -which is not straight at all- Corlack is about 6 feet tall, but if he were able to stand upright he would likely be closer to 8.

His right arm seems to have also suffered from the brutal hit he took, and it cannot move up more than midway to his chest. The hand hangs limply, completely unusable.
