I just tried it on myself and it produces some wierd colour distortions, particularly around the eyebrows, even with the default 'low' setting (50 iterations, threshold 0.003), so I'm not sure people will be happy using it. Kind of looks like I've been attacked by a bad eyebrow pencil. Also looks a bit like a picture printed on thin magazine paper (something trashy like OK! Magazine) held up to the light, so the image from the other side bleeds through.

If you tweak the values a bit lower it doesn't look so bad, but of course I haven't tested it with an array of DL algorithms.
