Alyssa - Practice in PS

I've got this sudden obsession with learning how to retouch photos and add makeup, much to Lenny's chagrin. I keep stealing His pics to do it with. But, I mean, come on! The model is stunning!

This is Alyssa. A friend of ours. Not sure what happened to the last pic of her I worked on. I think I used the wrong color space or something... heh. Leave it to me.
