Are you using a 3-point light setup for your promos?

It's probably to best start there, have your rim light shining towards her and off one over her shoulder so she's popping a bit from the background. The 3 point set up will also give you a light into your eyes to show reflection. 

You don't need too elaborate setups for lights in promos. They just need to pop the character from the background and allow you to show texture and morph details in neutral light.

Totally agree, and I used it for the promos that are there now (tho they're too bright and contrast), that's what I'm planning to use with softer shadows and not being too bright.  I'm just wondering if I'm using the wrong settings somewhere for the hair, as it looks too defined.  Or do you think the hair looks fine?  I don't. Still playing around.  Also gonna play with Depth of field lol this may give it a little more punch!
