This picture has been processed in GIMP from the former picture.

For white and black conversion, the image was split out in layers using colour channels.
I duplicated each of the channels in order to get a black and white background from the combination of the red, green and blue channels.
Above that, I applied tints to the red and blue channels with layer masks to control the tint of each layer, and I used the green channel on top of them with just black and white to preserve the white colour of the eyes (edited with the paintbrush to get them whiter).
I used the red channel for midtones, as it was an easy and comfortable way to get rid of skin imperfections.
