100% GIMP/Raw Therapee practice, just a snap otherwise.

Canon T4i
Canon 40mm f/2.8 STM
PP in Raw Therapee and GIMP

Gritty deets:

• RT
  • Exposure comp
  • Black levels, shadows down (too noisy otherwise)
  • White balance on the off-white-towards-blue wall behind me, adds a warm cast to the picture
• GIMP
  • Black and white through desaturate (luminance)
  • Split toning on orange and teal, just to be a jerk
  • Create a mask for lights and darks
  • Apply light mask to an orange colorized copy
  • Apply dark mask to a teal colorized copy
  • Skin smoothing
  • Wavelet decompose
  • Successive gaus. blur on wavelet layers
