It's all in the eyes. Go look at the official character art for the same soul across different cycle guidebooks. The artist changes the shape, the makeup, the setting, but there's always a specific light, a particular sharpness or depth in the eyes that's identical. That's where the soul lives. The clothes, hair, and even facial structure can change, but the gaze is a constant. Any adaptation that nails that—having the actor or artist convey that same essential 'look' through different faces—will sell the evolution. It's the visual proof that underneath the evolution, something unchanging and permanent is watching, learning, and enduring through it all.
