The usual miss
Phones make it far too easy to walk right up and fill the frame. The trouble is that up close, the lens exaggerates whatever sits nearest to it — usually her nose and forehead — so the face quietly stretches and widens at the edges. People blame the camera, the angle, even themselves. It's none of those. It's the distance.
The closer the lens, the bigger the gap between "how far her nose is" and "how far her ears are" — and that gap is exactly what makes a face look off.
