High to sharpen the faces of all persons

[inkdolls]

Sorry, this is not totally related to Gimp, but I just couldn't resist, I had to run this with GFPGAN. For this low resolution, it might work.

   

This one from Denzjos' image. The result is a mismatch of detail in the faces and clothes.

   

I still get a kick from this face restoration thing.
