I asked the Grok to render my "Javert" pencil sketch into a real person. Because of the pencil marks and battle scars, one of Grok's rendering showed the scars as tattoo, making me lose my lunch. I won't post that one here, in fact, I didn't save that rendering because that isn't me. I have no tattoo. Even Johnny Depp in 21 Jump Street said 3 times at least, very sternly that he would not get any tattoo. That was before he became a freak.
I am liking the first non pencil rendering. It resembles me when I was a kid and has that "Man In The Iron Mask" vibe with Leonardo DiCaprio going.
