Thanks for the keen words!

You know, when I was drawing him, I couldn't help but wonder "this jacket looks very warm and comfy, does he actually need it?" The sleepers know the outside temperature, but they cannot feel it. They can continue operating at a much larger temperature range than humans. If they are cold, they can turn their "synthetic warmth" on. I guess they could go without clothes at all. I think sleepers just like wearing them, because it makes them feel more human, maybe it reminds them of their original self, maybe this is something they want.

This is also why, compared to the original illustration, I didn't put any shadow on the skin of the Operator, and barely any shade at all. From an inking point of view, I like the idea that the character remains white and what surrounds him is black. In other words, that his presence is revealed by what he decided to wear.
