Dynamic video prompt, realistic selfie-style portrait of a woman cosplaying as Sailor Saturn, handheld phone perspective with slight high-angle tilt. Camera jitters subtly as her outstretched arm moves, motion blur emphasizing small hand and phone movements. Detailed violet-and-white sailor uniform with gloves, pleated skirt, and shimmering silver chest brooch reflecting light dynamically. Short sleek black hair with violet tones flows slightly, silver tiara and glowing violet contact lenses catching subtle highlights. Silence Glaive positioned in background, shifting perspective slightly with camera motion. Background of convention hall or softly lit room, starry aesthetic overlays subtly moving, natural flattering lighting, smooth skin tones, reflections on costume changing with motion, extremely dynamic, immersive Sailor Saturn selfie video style.
