You must be talking about this model.

I updated the textures based on DJM. Here is the diffuse.

And here is the rough map I made for it.

I think the cavity map had too much black in it for my intended look.
The sides of the lizard are supposed to stick out. The normal map didn't do very well on that part of it. Maybe I can show you the sculpture.
As for the dog creature, he has big muscle there.
