I'm a big fan of photo retouching, but there's a limit to what I like to do to photos.
Although it's sometimes just fun to mess with the shapes and features of someone's face, I prefer a more 'natural' change. Just an enhancement as opposed to complete facial restructuring. So it's highly unlikely that I'll be posting a tutorial for that specifically.
But I'm sure someone else will be able to come up with something.
As for the kind of 'enhancements' I generally make to photos, you can see an example from the changes I've made to a photo of Lisa's face below. I've added some eye shadow, eye liner, a bit of lip gloss/lipstick, changed her eye color, sharpened the focus on her eyes and lips and smoothed out her skin (including removing some birth marks). I like for people to look at the result and think 'Hey, I never thought I would look good that way.'
