(continued from previous entry)
fun part starts with a blank canvas. i added a simple circular gradient as a lighting guide, roughly following the thirds rule, to better bring attention to the main subject (the girl sitting by herself)

i then added partial luminosity of the cleaned up image in amounts following the lighting guide (20% of the couple closest to the subject, 35% of the middle couple, 50% of foreground couple, etc.)

a slight addition of the colors to check that they don't radically change the desired lighting.
