@lunabright3 A handheld selfie vlog-style video in vertical 9:16 format.

Luna stands near a quiet corner of the street, holding the phone with one hand.

The camera shifts slightly as her grip adjusts.

She subtly changes her stance, causing a small movement in framing.

A faint, natural smile appears and disappears — not held on purpose.

Her eyes soften as she looks briefly into the camera.

Mood: something small is working, slowly.
