nice.
when taking photos of the persons with problematic skin (women especially;-))
i always ask them not to use skin powder in order not to have skin tone changed.
you probably had it too greenish (due to the powder), and then hit autocolor or something that reduced green tones but drove too much of magenta tones on (it is visible on the haircolor too).
it is nice you have payed attention to the hand skin too, many retouches focus on face only.
your next step (only in fashion photography, though) will be subtle warping of certain section of the face
in order to shrink/shape the nose, lift up the eyelids or face sections and so on..
be careful with lower eyelids, so many editors completely remove those making people bit Far east looking.
this is of course ok if they are actual from far east.-)
