IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as the primary reference, strictly preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics. The transformation should apply the ancient Roman legionary aesthetic while maintaining 100% likeness of the original person in the photo. Do not alter the fundamental identity; only change the clothing, armor, and background context.

TRANSFORMATION DESCRIPTION:
Transform the subject into a battle-hardened ancient Roman legionary soldier from the Imperial period. Apply a historically accurate Roman lorica segmentata (segmented plate armor) over a red tunic (tunica). Add a leather pteruges (skirt of leather strips) and a Roman military belt (balteus). The face should retain the user's original features but with subtle, realistic grime or dust from a march, blending seamlessly with the skin texture. The expression should be stoic and determined, fitting for a Roman soldier.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Cinematic photorealistic, resembling a high-budget historical film or a detailed digital portrait. Highly detailed textures on metal, leather, and fabric.
- Lighting: Dramatic, volumetric lighting with a warm, golden-hour glow. Soft rim light outlining the armor and helmet. Shadows should be deep but not obscuring facial features.
- Color Palette: Earthy and desaturated tones. Dominant colors are rusted iron, aged bronze, deep crimson (tunic), and leather brown. The background should be atmospheric and muted to keep focus on the subject.
- Background Treatment: A blurred ancient Roman military camp or a misty battlefield in the background. Slight depth of field to ensure the face remains the sharpest element.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, ultra-sharp details on armor and facial features.
- Sharp focus on face and eyes; ensure the eyes are clear and expressive.
- Professional quality, 8k, masterpiece, trending on ArtStation.
- Aspect ratio: 1:1 (square) or 9:16 (portrait) depending on the original photo orientation.

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic armor proportions, blurry face, loss of likeness, cartoonish style, low quality, pixelated, deformed hands, extra limbs, modern clothing, fantasy elements, bright neon colors, oversaturated colors.

USER CUSTOMIZATION:

FINAL INSTRUCTIONS:
Ensure the helmet (galea) is placed appropriately on the head or held under the arm if the face needs to be fully visible. The lighting should highlight the metallic sheen of the armor without washing out the skin tones. The integration of the costume elements must look natural and physically plausible on the subject's body.
