Here Be Monsters 伦敦海报

Goal: Create a dark animated graphic-novel movie poster for {argument name="title text" default="HERE BE MONSTERS"}, showing a ruined monster-occupied London under a stormy night sky.

Canvas: Vertical poster composition, 3:4 aspect ratio, high-detail 2K cinematic illustration, gritty hand-drawn comic ink style with painterly shading, muted charcoal greens and browns, harsh golden highlights, heavy texture, dramatic contrast.

Layout: Place a huge jagged brush-lettered yellow title across the top third, slightly tilted and overlapping the creature behind it. Behind the title, fill the upper half with one colossal eldritch winged monster looming over London: massive bat-like wings spread edge to edge, dark scaly body covered with many clustered eyes, tentacled octopus-like face, long curled appendages, partially hidden by smoke and clouds. Put the full moon glowing near the right side behind the creature. In the lower half, show a militarized barricaded London street with gothic architecture, Big Ben on the right, spires and ruined buildings on the left, smoke, rubble, soldiers, vehicles, and street lamps.

Foreground characters: Exactly 3 human survivors stand across the bottom center, walking toward the viewer with serious expressions. Center character is {argument name="main character" default="a bald muscular middle-aged man"} wearing a dark tactical hooded jacket over black clothing, stern face, broad shoulders, central heroic stance. Left character is {argument name="left character" default="a young man with short messy black hair"} wearing a dark jacket and shirt, slim build, intense downward gaze. Right character is {argument name="right character" default="a blonde young woman with a side braid"} wearing dark layered clothes, sharp glare, hair blowing slightly.

Background details and text: Include exactly 5 readable text elements: 1 large title text “HERE BE MONSTERS” at the top; 1 central checkpoint banner reading “WELCOME TO LONDON CITY”; 2 vertical propaganda posters on either side of the gate reading “KEEP CALM AND CARRY ON”; 1 small repeated sign or poster fragment may be partially visible but should not introduce new wording. Add a fortified gate, sandbags, scaffolding, armed soldiers, and a military vehicle on the right. Include exactly 3 ornate Victorian street lamps clustered at the lower left.

Visual style: Dark fantasy horror meets post-apocalyptic London, adult animation concept art, expressive ink outlines, dense linework, moody fog, smoky atmosphere, limited palette with yellow title as the strongest accent. The image should feel like a lore-book cover or animated series poster.

Constraints: Keep the title legible and dominant, do not use photorealism, do not add extra main characters, avoid clean modern typography except for the distressed hand-painted title, no watermark, no logos.
