Sim Shepard: Close enough?

Been plugging away at this Sims 4 version of my Shepard, because it's important that I get it right. (Did I mention my self-sim has the perfectionist trait?)

I know it's not there yet, but I'm not sure if I can do better than this.

Actually looking at them side-by-side is helpful, I hadn't really done that until composing this post. Hmm, yeah, I think I need to work on the ears, that shouldn't be a problem. And the jaw and cheeks definitely need work.. or maybe pull the face up a bit more? Or wider? I don't know.. Will play around.
