1 & 2 are pretty true to SOOC exposure. I adjusted contract, masked in saturation on the tutu, defog, took out a bit of yellow, used healing brush under the eye reduced opacity of the layer, sponged out some redness under the eye(she has a cold) at 32%(I think) desaturation, masked in a surface blur and then adjusted opacity to taste. In this case I lasood the general eye area and brightened them with curves in a seperate layer, then erased the eyelids and bridge of nose back, lowered opacity and erased the whites of the eye back. I don't sharpen the eyes seperate but her iris is a very dark gray blue so I always find myself brightening them.
The last one was actually the first photo I took with just light from a window and I underexposed it. So I brightened the backdrop with the white curves eyedropper on a white speck in her eye, then erased her back at a lower opacity adjusted curves and contract to get desired brightness and did all that other stuff to her.
That sounds like allot but it really didn't take to long LOL
