Epic Dark Fantasy Scene with Grotesque Masks

Create a highly detailed dark fantasy illustration in the Flux:Bradhamel art style. Render this from an elevated rooftop perspective, looking down onto a fortified city square below bathed in cold, stormy light. A massive spiral of white masks engulfs the upper left area, stretching impossibly high into the swirling weather; these masks range dramatically from colossal door-sized faces looming near the ground to faint, pale streaks blending into distant storm clouds. Each mask within this horror show exhibits grotesque anatomical features: elongated noses dripping with condensation or gore (depending on mood), and mouths agape in silent, chilling rictus. Directly below this oppressive spiral, standing stoically on a weathered rooftop stair at the lower right of the square, is a grown woman standard bearer. She clutches a tattered black banner across her body with fierce determination. A curved red energy barrier emanates from her hands onto the banner, forming a jagged shield that visibly stops and repels several masks just before they reach the open city gate behind her – creating a clear path for a small group of refugees to emerge into the stormy night as she vigilantly guards it. The scene must capture Flux:Bradhamel's signature detail-to-color ratio, atmospheric depth, and dramatic chiaroscuro lighting typical of dark fantasy, utilizing the illustrative power of WatercolorInks, ensuring a masterpiece quality execution.
