Important:

The default scarjo comes out red hair and looking not much like her. It's important to use keywords like "blonde", "half body shot" and maybe something like "ponytail" / "pigtails" if you don't like the default hair.

This will be fixed in a future release.

Didn't like any of the other scarjo models out.

I can see why they fail. It's ridiculously hard to find pics of the scarlett johansson we all know. Most screencaps and pics of her receiving awards look like a completely different person.

I went through a bunch of movies and meticulously screengrabbed all the microexpressions she does in pics that represent her well.
