using Photoshop:
- Used a LucisArt filter to sculpt the image.
- copied original image on top and set mode to color to fix color shift in lucisart
- created a channel mixer adjustment layer set to monochrome, upped the red, lowered the blue. Set opacity to ~75% to allow a bit of original color back in
- masked out the hair of both girls
- added a solid color adjustment layer set to a dark brownish color, masked out the hair again, and lowered the opacity to ~30%
