“Cyberpunk city, ultra detailed, 8k” is a mood, not a brief. On Nanomelon it usually returns a crowded night street with random glyphs, melted signs, and a face that changes every click. This case study walks one scene from a weak prompt to a stable plate you can reuse for posters or character art. Read it alongside prompt structure and commercial posters.
Weak prompt: “cyberpunk girl in neon city, masterpiece, best quality.” Problems: no age band or wardrobe materials, no camera distance, no light direction, no medium (photo vs anime), no negative space, and brand-risk neon logos invented by the model. Aspect ratio often left at square by habit, then cropped—another waste.
Outcome pattern: pretty noise. Credits leave the account on “successful” images you cannot use in a layout. Policy may also trip if the model paints a famous franchise look.
Better prompt skeleton: “Young adult woman in a mid shot, black rain jacket with matte vinyl texture, holding a closed transparent umbrella, standing on wet asphalt that reflects cyan and magenta storefront light, steam rising from a sidewalk grate, generic neon signs with unreadable shapes (no brand names), shallow depth of field, photographic, night, soft face fill from sky glow, vertical 3:4.”
Why it works: vinyl, umbrella, grate, and wet asphalt are objects the model can place. “Unreadable shapes” reduces fake trademarks. Photographic medium steers away from default anime eyes if that is not what you want. 3:4 matches a character poster.
Keep the Version 1 text. Change only light: “replace sky glow fill with a single magenta rim light from camera left, face mostly in soft shadow.” Run quantity 1. If the rim is too harsh, revert and try cyan rim instead. Do not also change jacket color, hair length, and ratio in the same click. That is how people burn starter credits without learning which clause mattered.
When the face is good enough, switch to image-to-image for wardrobe or background only. Prompt: “keep face and pose, change jacket to olive utility coat, same wet street.” Restating “cyberpunk girl…” as a full text-to-image brief risks a new identity.
If you want illustration, say so early: “cel-shaded anime illustration, clean linework, limited palette of teal and pink, city background simplified, character mid shot.” Mixing “photoreal skin” with “anime eyes” in one sentence produces hybrids that look accidental. The dedicated guide anime vs realistic covers A/B tests; here the rule is medium-first.
Name hues as light sources: “cyan tube light under a metal awning,” “magenta LED strip along a curb.” Avoid “Blade Runner,” “Akira,” and named game titles. Avoid real soda or phone logos on billboards. Generic “kanji-like marks, out of focus” is safer than inventing readable foreign text you do not control.
Long object-list specimens such as gallery 105 show how props carry a night scene. Short mood fragments like gallery 153 show what happens when the brief is thin—use them as counter-examples, then rewrite with the Version 1 pattern.
Once the street plate works, leave the upper third relatively dark or flat for a title. Composite real type offline. Asking the model to add “OPEN 24H” in sharp Latin letters usually fails and clutters the midground. See the commercial poster guide for the three-pass credit budget.
Keep sexualized minors, real-person deepfakes, and hate symbols out of trend-style experiments. Public gallery submissions go through automated filters and staff approval; prohibited categories are listed in community guidelines. Client or unreleased work should stay private so prompts are not exposed.
If any box is empty, you are still on Version 0.
Plan four clicks maximum: Version 1 plate, one light tweak, one img2img wardrobe tweak, optional second light. Stop when the plate is good enough to composite type. Chasing “more neon” for ten successful generations teaches the meter, not the craft. Prefer one model for the whole session so skin and reflection behavior stay comparable across A/B frames.
If the model list changes later, upstream pricing or availability moved—save the stills you like, not only the model display name. Failed and policy-blocked jobs do not deduct credits; use that safety net to rewrite the object list, not to spam Generate with the same Version 0 sentence.
Paste the Version 1 skeleton into the homepage prompt box, set 3:4, quantity 1, then change only light on the second run.
