Tips to refine this prompt

Adjust aspect ratio (--ar 3:2, --ar 9:16) to match where you’ll publish.
Increase --stylize on Midjourney for more dramatic interpretation, or lower it for fidelity.
Add a strong subject anchor at the start (e.g. “close-up portrait of…”) for tighter composition.
For Stable Diffusion, refine the negative prompt with words like blurry, distorted, watermark, low-quality.
Re-roll 4–8 times — the same prompt regularly produces very different compositions.
