Dirty Little Feet

This is a little sister of a girl that plays on my daughter's soccer team. How can I get the skin a little darker/pinker with out making it look too fake.

For me the skin tone is already pink enough and looks decent in shot 2. Good eye sharpness.

In shot one skin tone is a bit light, just a bit. I'd simply burn it in. The tone of the skin already looks pink enough to my eye.
