Sentient En Noon
Rather good. Robots are awkward to display emotion well (due to static expressions), so it's interesting to see that you've flipped this and turned it to your advantage: a robot with a constant expression of agony. Did the creator choose the human form and its emotions to torment it? Who knows.
Face details are excellent, along with the body work and the red glow coming from behind the body ... with some light passing through the body cavities of the bot.
Hmmm .... cables could use some slight highlights, and I'm not sure if the white light is embedded in his chest or hovering in the air (for whatever reason), due to how you've highlighted the chest. Otherwise I'll give you a perfect 10.
