I think the toes are pretty sharp so maybe front focused. But the fingers look pretty grainy, too grainy for ISO 100. Maybe some odd compression. Does the RAW look like that?

What did you use to create the lighting setup diagram?

Tripod?
IS on/off?
One shot/AI servo?
Are you focusing on her eyes & then recomposing or selecting a focus point?

Here you go...
Tripod - No (very mobile target, needed to be able to adjust)
IS on (standard/mode 1)
AI Servo
Selecting the closest focus point, but then had to recompose a tiny bit

Anything jump out?

Yeah, grainy, that's exactly what it looked like to me, which made no sense with the settings. And yes, the RAW looks the same to my eye (not necessarily the most highly trained eye for pixel peeping yet). The original was a little underexposed, not sure if that could do it?

servo will jump around when recomposing. use one shot.

I use back button, then recompose after locking in focus and releasing, that should negate that, right? Obviously I'm using the term "locking" a little loosely here... :)

yes it should.

i would still switch to one shot with a sitting subject. but it's just my preference, really.

That is exactly how I use servo. Once you let off the trigger, focus isn't moving.

OP:
Take this with a grain of salt. I am not a professional. I like the second shot a lot better. The only - slightly annoying - thing that stands out to me is the hots spots on her extreme right neck, right shoulder of her clothing and right arm. I am assuming you moved the umbrella closer. If the umbrella is just out of frame, you may be better off to turn it around and point the flash into the umbrella as usual, but point the umbrella away from her. I use cheap, thin shoot-through umbrellas that generate those types of hot spots. Using them as reflectors instead solves the problem for me. Oh, and deploy the diffuser panel, if you aren't already. It helps fill the umbrella, no matter which direction the flash is pointing.

"Locking" focus in that sense only applies to One Shot. Even using back button, with AI Servo, the camera will track where you've locked the focus. When you move to recompose, it refocuses because it seems that the subject is moving. I think you either need to choose and use a focus point on her eyes, or change to one shot and lock/recompose.

You are misunderstanding the use of BBF and Servo. Once you have "lock" you release of the focus button on the back, the focus will not change until you press the button again.

See quoted post below.

THAT is how bbaf is used, properly.
