In my culling process, I'd 4-star this one. It's good enough to use IF you really don't have any others to use from that pose. But of course if you had an equivalent 5-star, you'd ditch this one.
I guess you need to reorder prints of the exact same files you printed the first time.
If they come back looking different, you'll know it's a lab problem.
Well, we need to try to figure out why your screen matches one set of prints but not the other.
Can you think of any tiny reason why they might be different?
There's no quick way to do it. You just have to add a Levels layer and pull the black slider in aggressively (suggest to about 90 for this one) then invert the mask, then paint on patiently with a 10% brush.
Gosh, that's SUCH a good question, with no straightforward answer.
You'll need to try it both ways - with the skin layer set above, and below, the artistic layer set, to see which you like better.
