Prompt craft for ComfyUI generation

Prompt craft for ComfyUI generation

A prompting approach, practice-tested on Flux and Anima-like models. The examples below are neutral; the technique applies to any content.

Two prompt formats

Format	When	Example
Danbooru tags	simple scenes, portraits, standard poses	1girl, blonde hair, sitting, park
Literary text	complex poses, unusual angles, many planes	A girl sits on the edge of a bench, adjusting her hair, seen from above

Key insight: the literary format instantly solves composition that tags can't handle — the model understands spatial relationships better in free text. Flux is especially fond of literary descriptions along the lines of "a girl stands among bushes in the middle of the street", NOT a comma-separated list of words. Caveat: some LoRA are trained only on tags — test your own stack.

Quality prefix

masterpiece, best quality, newest, highres

Avoid score_5, score_6, year 2025 — these are artifacts of other people's LoRA.

Principles (critical)

1. Composition goes in the first 3–4 tags. Angle and pose BEFORE appearance: profile, from side, sitting on chair → then hair, clothes.
2. One tag per concept. Not five synonyms for an angle — just one (from below).
3. Negatives DON'T work. The model doesn't understand no door. Describe what SHOULD be in frame, not what shouldn't.
4. Remove the conflict, don't compensate. A tag conflicts → delete it. "Fixing" tags bloat the prompt and spawn new conflicts.
5. Overloaded → rewrite from scratch. Don't patch a bloated prompt — reset to 15–20 key tags.
6. Literary drifts into photorealism → fall back to tags. If 2+ attempts produce photos or break anatomy — return to Danbooru tags (they're more reliable for simple/medium scenes).
7. Numbers in tags break the counter. double bun → hair bun, two buns. Don't mix solo and 1girl.

Anti-patterns and fixes (neutral)

Problem	Cause	Fix
Two characters instead of one	double bun (the word "double") or solo+1girl	hair bun, two buns; remove solo
Character with back to the window	front lighting + sunlight from window conflict	remove front lighting
Full body instead of close-up	sneakers, asphalt, full body pull the frame out	remove shoes/ground, keep close-up
Red instead of orange	red hair	dyed hair, orange hair
Character on the couch instead of the floor	sitting on floor, leaning against couch	sitting on armrest; remove couch
Twintails → huge bows	twintails triggers decorative ribbons	low twintails, small hair tie, elastic hair tie
Crouching instead of standing	standing without qualification	standing straight, upright
Photorealism from literary	photo terms: shot, camera, cinematic, overhead	describe the scene: seen from above, looking down at
Name collision in a batch	identical filename_prefix within a second	unique prefix per job: batch_{i}
