If you enjoy creating people with AI, you might want to consider looking into facial restoration software. This example still needs work but most of the work is done. The kkin is less grainy, there is less of a green cast, the hair is smoother, and his eyes look more finished. Though I would still trade out the irises from a number of them that I've collected on those rare occasions when AI creates some decent ones.
