Jayden for M4 was the texture used in those images.

Another thing I tried:

I tried faceshop to make a younger M4 face from a photo of a young man who was the look I wanted for the character.  The one time it ran to completion the face was decent, but ended up not looking like the young man in the photo.  It looked more like a 35 year old version of him.  Since then it has crashed every time before completing.  The texture it made was black.
