The texturing here is incredible - the soft gradients on the flesh tones vs the hard color clusters on the metal, and the way the former get shaded more like the latter where the "biotech" is most evident; the rendering of the hair; the almost subliminal hints of a... smirk? grimace? indicated with just four little pixels... just masterful. I love this.
Excellent work. I love the lighting on the different materials, and the skin shading is great.
its perfect!
