Gothic Vampire Sisters

Create a richly detailed vertical anime gothic-fantasy illustration of two young vampire sisters standing face to face in an ornate Victorian mansion at night, laughing joyfully with eyes closed while clasping both hands together between them. The left girl has {argument name="left character hair color" default="lavender-blue"} short wavy bob hair, a frilly pink maid-inspired dress with red ribbons, a large white mob cap with red trim and a huge dark red bow, small black bat wings, and a soft mischievous smile with tiny fangs visible. The right girl has {argument name="right character hair color" default="golden blonde"} wavy side ponytail hair, a deep crimson frilly dress with white ruffles, matching white mob cap with a huge dark red bow, black wing-like crystal frame behind her, and a matching delighted fangy smile. Include exactly two main characters, posed symmetrically in an intimate sisterly moment, hands interlocked at chest height. The background is a dark luxurious vampire parlor: heavy burgundy curtains, a tall window showing a huge glowing {argument name="moon color" default="blood-red"} full moon in a cloudy night sky, antique framed portrait on the left wall, lit candles, an ornate chandelier with many warm candle flames and dangling prisms, a vintage clock on the right, red velvet furniture, dark wood, gold trim, and a moody patterned carpet. Add exactly six prominent colored hanging crystal prisms near the right character: red, green, purple, pale blue, dark blue, and clear-blue. Use dramatic warm candlelight mixed with cool moonlight, glossy fabric highlights, intricate lace and ruffle details, soft painterly anime rendering, high detail, romantic gothic atmosphere, no text, no UI, no watermark.
