Sure... Hair was separated and retouched on its own Contrast/Unsharp mask/saturation/Selective color +magenta in the red
Skin: first take the mayor pimples out with patch tool
Then duplicate the layer high pass filter at 9%/Glausian Blur at 3%/invert layer/Mask to hide/Then paint white witha very soft brush on the skin.
Change skintone with selective color (-50 Magenta -15 Yellow -80 Black APROX)
Then on the top: D&B Set of layers
Curve Lighten/lighten the midles (Masked to hide)
Curve Darken /Darken the midles (Masked To hide)
On the first one, paint white with a very very small soft brus (Zoom like 1o00%) to take out dark spots on the skin and a bigger brush to bring nice highlights to hair, arms, body
On the darken, the same, with a small soft brush paint white on the points you see need to be darker. And with a soft not so small brush acentuate the shadows on the hair to add depth and the edges of the body.
Hope that's clear inoff, my english is not native (In fact, I've never studied english) so it's not so good.
