Realistic Monster Character Model

I have a full turnaround sheet for a metallic-skinned creature that needs to become a drop-in, game-ready asset. The look is realistic, so I’m expecting believable muscle forms, true-to-life material breakup, and detail that will hold up to close-ups as well as silhouette reads from a distance...
