Well as a beginning you've made a reasonable start
on the skin, you still need to do a lot of work on colour and tonal range - despite some of the advice, you certainly don't want to be introducing texture in this particular shot because its good enough to begin with, theres nothing there that cant be achieved with proper detail technique. You will be destroying all your hard work. Remember you can retouch skin texture IN as well as out, in various ways.
Study some makeup, because this needs to be worked up, her face is too matt and 'foundation' at the moment - her eyeshadow done properly, eyelashes realistically extended will help too.
