There are two images - "Base" and "Reference" to be looking at, the second will be posted immediately after the first image - unsure if this is feasible due to lighting & shadows.
1. Using the reference picture, try to shift the color of the hair in the base image to be as similar as possible, accounting for the dark setting/shadows
2. Try to avoid any color changes whatsoever besides from the hair
3. Extend the image about 10% to the right (it's mainly darkness regardless)
4. Extend the image about 5% to the left (the main focus here is trying to make sure the torch can be extended properly - if not, then stop at #3)
It's likely a bit much to ask for, though I hope at least a little can be done.
