"NOVA"是一张万圣节背景图,采用写实的夜间墓地风格。靛蓝色薄雾中有飞着蝙蝠的满月、亮灯的鬼屋、墓碑、铁栅门和发光的南瓜灯,底部中央有一块写着NOVA的小金属牌。你可以把牌上的名字换成自己的频道、团队或派对名称,并利用空旷的夜空添加标题或详情。

Create a finished 16:9 spooky Halloween livestream background in a photoreal moonlit-graveyard style. Keep the central 50% of the canvas—roughly x=25–75%, y=18–82%—open, dark, and visually quiet for a webcam feed: a smooth deep indigo night sky fading to subtle low mist, with no moon, lettering, props, or bright details in this webcam zone. Frame it with graveyard scenery kept to the outer sides and bottom. At the upper right, place a huge full moon with a few small bat silhouettes crossing its face. On the left edge, a crooked haunted-house silhouette with a few pumpkin-orange glowing windows rises behind a bare twisted tree. On the right edge, add a crooked iron graveyard fence, sparse gravestones, and another twisted tree. Along the bottom corners, place a small row of jack-o'-lanterns with restrained candle-orange glow; leave the bottom center clear except for one small nameplate. Cool moonlight rim-lights the silhouettes; pumpkin lanterns and house windows are the only warm light sources. Deep indigo-purple night, soft drifting mist between gravestones, subtle fine grain, clear silhouettes, no busy detail in the webcam opening. Set the exact text "NOVA" on a small, centered, dark iron nameplate at the bottom, below the webcam area. Render the name in a bold, upright display sans with open counters and small bat-wing flares at flat stroke ends; keep every letter immediately readable. Moon-white lettering with a restrained pumpkin-orange edge glow. No other text, logos, borders, or overlays.
