Acheron Fauvist Strong-Color Dynamic Slash AI Image Prompt

Fauvist strong-color figure. miHoYo character: Acheron (黄泉) (Honkai: Star Rail / 崩坏：星穹铁道), directly use the character's adult female identity and recognizable appearance cues: purple-white gradient long hair, cold white skin, wandering swordswoman aura, black-red-purple asymmetrical trench-coat silhouette, single-side shoulder-armor silhouette, solitary and resolute aura; but must remove the original game splash-art feel and remove miHoYo official anime rendering; do not let the original character art style affect the image. The image is a vertical character key visual: Acheron strides from the right side of the frame toward the lower left while lowering her body to draw her sword, her body forming a highly tense large diagonal composition; one hand presses a rugged abstract long scabbard, the other grips the hilt, trailing a thick bright-red sword-light color block. The background is pieced together from unnatural pure color blocks of electric purple, magenta, bright yellow, cobalt blue, and deep black; the cracked sky and giant blood-moon shadow are exaggerated into rough brushstroke outlines. Use 'Fauvist strong-color figure' as the specific style anchor, focusing on unnatural high saturation, rough brushstroke outlines, free color planes, clear figure mass, and clear planar-spatial relationships. The composition must be a full-body large dynamic slash, low-angle side candid capture, strong diagonal large color-block cuts; no centered portrait, no sci-fi realistic game poster, no fine anime coloring. Subject is adult, face clear, hands natural and accurate, image clean, visual focus clear; no random text, logo, watermark, or brand names; no real celebrity face, no childlike look, no excessive nudity. Ratio 9:16.
