Ehhh Potentials -

demure, fine-featured

We could look for vocabulary words to describe the eyebrows, the eyes, nose, baby hairs, etc. nothing is top of mind for me right now though.

I'm riding in the car, but I'm not driving, so technically I could be considered a ""passenger princess""… or just a passenger really, but I think I'm searching more for the vibe from the face or how the face is being lit up.

Even though the image is taken at night, I do not think “noctivagant” (“walking or wandering in the nighttime; night-wandering”) really works, since wandering mostly gives me a walking vibe, or maybe a motorcycle or horse.

Anything involving reflections works with almost any mirror selfie, I suppose.

I think K-pop artists might be a goldmine for facial expressions that could be paired with dictionary entries. I'm pretty sure these companies are extremely meticulous about training their stars' facial expressions for almost every public-facing appearance. Anywho, here’s a random BLACKPINK song: https://youtu.be/9pdj4iJD08s
