Finished roughing out the arm cybernetic bump maps and played around with some material variations. Need to refine them in Photoshop, bake normals, and texture the "seam" inlays and other miscellaneous details. I'm also considering adding some cybernetics to her legs/torso, but I don't want to overdo it; usually less is more and I don't want to draw too much away from Ellie's original likeness.
