Hi Triske,
I'm new here myself and this is my first post of any kind. Of the two attached versions of your files, as a photographer, I prefer the second, the first is a little overexposed.
While you may be new to
PS or
PSE, your greatest control for this image is with your Raw converter, not
PS since you shot Raw. I would agree with blue dog's comments regarding white point (white balance set too cool). Try a "warmer" temp.-higher number- for the white balance. Avoid pushing the black point (shadows) too high as you'll loose detail in the shadow areas. Also, high contrast, while desirable in many types of photographs, is not particularly well suited for this type portrait.
Using the second image and the Shadow/Highlight controls in
PS, I opened the shadows a little (note detail in hair). Also, tweaking the highlights and lowering the mid-tone contrast slightly added more color back to the ladie's faces.
