Okey dokey - heres what I did.
1 Duplicate Original
2 looked at the individual channels R,G,B and adjusted the sliders as previously discussed on each channel.
3 decided that a mask was the order of the day, hopped to channels again and used a combination of them to make my mask. (to make mask press q [quick mask] any mark you make with black as your brush colour will now in effect conceal portions of the image, white reveals it. the idea is to paint black as much of her and the donkey as possible. When you have finshed, press q again to reveal the marching ants. Ctrl + Alt + D and feather the selection by 0.5 pixels. Finally for this section select the lasso tool (L) and right click on the canvas - choose save as seperate channel.
To switch between the background and the girl and donkey use Ctrl + Shift + I , this will switch between the two.
Back in the layers from channels again. I added a new curves layer and altered the balance slightly, so that the light and dark tones gained more clarity and were less washed out. Play with whatever looks right.
With the mask activated (the marching ants) so that the donkey and girl will be effected, press Ctrl + U and increase the saturation slightly - the aim of this is to pump the colours back up to their original vivid state. Dont worry about the face being wrong, as this will be adjusted next. +7 - 15 should do the trick.
Now with your selection still active, make a layer mask (one of the small buttons near make a new layer [bottom right]) then drag a black to white gradient, so that the face is covered and back to the right shade, but the jumper and donkey still retain the boost to saturation.
Nearly there

I made a rough selection of the face with the freehand lasso and feathered it by 5 pixels. Pressed Ctrl + C to copy to clipboard then Ctrl + V to paste as a new layer. Gaussian blurred the new layer by 5 and set the mode to screen, lowered the opacity of the layer to about 10-20 %.
Finally using the mask again I selected the sea and made a brightness/contrast adjustment to whighten then foam and to darken the sea.
I have made it seem complicated but this way you are sure to pick up a broad smattering of Photoshop tips, shortcuts (not that I know any) might not be as informatively useful
