Moonlit Gothic Fantasy Couple — AI Image Prompt

Create a vertical fantasy romance illustration in a richly detailed Japanese dark-fantasy oil-painting style, with dramatic brushwork, luminous moonlight, deep indigo and violet tones, and a grand romantic atmosphere. Show {argument name="couple description" default="a beautiful silver-haired princess in ornate crystal armor embracing a tall black-haired nobleman in a dark formal suit"} standing close together in the foreground, their faces softly obscured by shadow or painterly blur to keep them anonymous. The woman has extremely long flowing silver-white hair streaming across the scene, a jeweled silver breastplate and shoulder armor over a layered translucent gown, delicate gold filigree, blue gemstones, and a cape-like train. The man has tousled dark hair, a black velvet-like suit jacket, white shirt, loosened tie, a gold crest brooch, and one hand in his pocket while the other side is held close by the woman. They pose intimately as if about to kiss, centered slightly right of the frame. Behind them is {argument name="castle setting" default="a towering gothic fairy-tale castle with many illuminated spires"} under a huge glowing full moon surrounded by swirling painterly clouds. On the right, include an ornate arched magical portal glowing with violet light and intricate cathedral-like carvings. Add exactly three visible lanterns: one large warm streetlamp on the left edge, one hanging lantern near the upper right, and one tiny distant lantern near the couple. Fill the lower foreground with purple roses and dark foliage, with drifting glowing petals and blue-violet firefly-like sparks. Use high detail, romantic fantasy lighting, moonlit highlights on metallic armor, sparkling crystalline textures, cinematic depth, painterly impasto strokes, elegant composition, no readable text, no watermark.
