Here's a shot from a work in progress, based of course on metlslime's design.

The animations are barely started, and I'm not happy with the legs yet. Also this is a 'clean' version aside from the chainsaw, no blood splatters yet. One of the reasons for this is the skin is mirrored at the moment, and Rorschach style symmetric blots of blood might look quite odd. The skin has been designed so that the seams of the torso and head lie along the left edge of the skin. So if there's no way to make the ogre work as it is, then it can be mirrored and the left and right sides will line up exactly. It seems a bit odd to double the dimension of the skin just to accomodate the blood splatters, but never mind.
Criticisms are welcomed, hopefully with them it can be made into a faithful substitute model.
