i have actually played with this photo a few times now.... while she is beautiful.. the mascerra did her no justice at all. it is hugely distracting. and your not in aww at how pretty she really is.. instead.. your thinking.. " whats up with the make up?"
i think if you play with this photo.. you can get some really nice results. i removed her eyelashes, and put some natural looking ones ( kinda) on with some photoshop brushes.. i cleaned out the spot on flash, and hand drew some catchlights.
it does give it a better feel.. but after a while you keep feeling like your going too far.. because you are working with a picture that has pretty hard light.. and that hard light makes the depth of face kind of go away, and it loses that three dementional look.
but as far as making the lips shiny, and same with the eyes. the suggestions that are listed above are key. and when you go to PP.. what cyber pet has done, is really outstanding, and prettly much standard practice when in pp.
but..you can use the plastic wrap filter in your filter menue. and adjust opacity, and sharpness of that to give a glossy feel. and i see some people do that on photoshop tutorials on you tube.. i think when done in moderation it looks ago.. but again.. it gets overdone really fast.
so i think starting off with the basics up front will always be key in getting what you want.
good lighting makes a world of difference. then the pp, and come in later.
err im rambling.
sorry.
