  • Positive Prompt:

    A cinematic synthwave-style poster of a colossal futuristic volcanic eruption. Centered in the composition, a massive volcano made of sharp, wet, reflective obsidian and basaltic slopes erupts with immense power. Glowing, highly viscous rivers of electric-cyan and deep sapphire magma cascade down the dark, jagged slopes, casting a brilliant bioluminescent blue light. Above the caldera, a massive, billowing ash cloud of iridescent violet, magenta, and deep purple swells into the dark atmosphere, crackling with jagged webs of neon-violet volcanic lightning. Volumetric light rays, glowing embers, and hazy blue particles float through the air, creating a rich depth of field. At the bottom of the frame, integrated seamlessly into the dark, misty foreground, the caption 'When the earth bleeds neon.' is displayed in a sleek, minimalist, glowing sans-serif cyberpunk font with a subtle cyan and violet neon outer glow. Masterpiece, highly detailed textures of molten glass and rocky terrain, high-contrast cinematic lighting, 8k resolution, professional graphic design.
