I would be able to give you a better analysis if her bra was on the floor. JK.
I like #2 it is brighter for one. Some say a little washed out, but her skin to me looks silky smooth in that one (Hitachi CM721F CRT is what I am using.) As far as the yellow, go with it! It is more natural looking. It looks like lighting from a halogen torchiere lamp. I like it.
Just my two bits, oh wait I don't have two.
