I've started working on an Idina Menzel sim for the Creator Challenge because she's a known Broadway actress, but I'm not sure if it really looks like her yet. I feel like it looks more like pre-plastic surgery Kylie Jenner at this point
Things I would adjust:
-The overall impression of her face is kind of long, I would lengthen the sim's face, and make her nose longer so there's less space between her lip and nostrils.
-Her jaw in the photo shows an underbite, but you have an overbite profile for the sim. Bring the jaw (not just chin) forward
-Her nose looks like it needs more projection in profile too, it's too close the the face.
