An anime / illustration prompt with a clear style reference.
Prompt
Cinematic 2D digital illustration, polished semi-realistic anime aesthetic, clean bold linework, smooth cel shading blended with soft painterly gradients, expressive detailed facial rendering, subtly exaggerated proportions, glossy eyes, natural skin texture, dimensional hair with individual flowing strands, warm rim lighting, {argument name="color grade" default="moody teal-and-amber"} color grading, muted vintage tones, soft ambient shadows, slightly grainy texture, {argument name="vibe" default="nostalgic 1990s/2000s editorial-poster"} vibe, atmospheric indoor lighting, highly polished character art, crisp details, depth and cinematic composition, vertical 9:16.
The output stays consistent because the prompt nails down a defined colour grade and a material / texture call, so re-running it — or handing it to a teammate — lands in the same place instead of drifting. Keep those clauses and rewrite the subject to make it your own.
