@lunabright3 A realistic handheld selfie vlog-style video, vertical 9:16.

Luna walks forward with an easy, unforced pace.

The phone is held casually, resulting in light, rhythmic camera motion with each step.

She looks ahead most of the time, occasionally glancing into the camera without stopping.

The framing shifts slightly as her arm moves naturally.

Mood: gentle momentum, quiet confidence.
