Ok, great. Here's the PSD
The order of doing things will need some explanation ...
Do the Channel Mixer layer, but leave its mask entirely white (so it affects the whole photo).
Add the Dodge & Burn layer and clip it to the CM layer, but don't actually do anything on it yet.
Add the Hue/Sat layer and clip it as well. At this stage, the whole photo will be pink.
Return to the D&B layer to do that work. Use a very low opacity brush and work gently and patiently, until it's all as smooth as you can make it.
Finally, return to the CM layer and invert the mask to black, then paint on the mask just on the area where needed. Make sure it's a biggish soft brush that blends out nicely.
