# Pencil Sketch Images with HiDream I1: Prompts, Examples & Best Settings

> Create pencil sketch AI images with HiDream I1. Get copy-paste prompts, settings, example directions, model strengths, limitations, and FluxNote workflow notes.

## Quick Answer

HiDream I1 excels at pencil sketch AI images, offering expressive strokes and tonal depth close to hand-drawn artworks at 7 credits per generation. It outperforms most models for artistic sketches with intentional uneven lines and visible paper texture, though it struggles with ultra-high photorealism. For best results, use detailed descriptive prompts referencing graphite weight, hatching techniques, and artistic styles like observational sketching or loose gesture drawings.

## Full Guide

HiDream I1 is FluxNote's most cost-effective model for authentic pencil sketch images (7 credits/gen), specialising in textured lead strokes and artistic imperfections. Its training on East Asian illustration datasets gives unique sensitivity to line quality, making it superior for: 

- Charcoal-like blended shading (specify 'heavy graphite pressure')
- Cross-hatched technical drawings (add 'precise architect-style linework')
- Gesture sketches ('30-second speed sketch marks with unfinished areas')

The prompt formula: 
[Subject] + [Action/Expression] + [Sketch Type] + [Artistic Technique] + [Detail Level] + [Paper Texture] 

Example specs:
1. Portrait: 'elderly man with wrinkles, side lighting, academic pencil study with chiaroscuro shading on cold-pressed paper' -- 1:1 ratio, 18 steps, style weight 85%
2. Animal: 'grey wolf howling, moonlit, field sketch with energetic scribble lines and erased highlights' -- 16:9, 22 steps, style weight 95%
3. Object: 'antique pocket watch, exploded-view technical drawing with ruler-straight construction lines' -- 4:3, 15 steps, style weight 75%

Comparisons:
- FLUX.2 Pro (18 credits): Better for hyperrealistic shaded drawings but less stylistic
- GPT Image 1.5 (18 credits): Stronger at textbook-style instructional diagrams

Failure fixes:
- Blurry lines? Increase 'sketch lines visibility' to 1.3
- Over-smoothed? Add 'keep rough underdrawing visible'
- Weak shading? Specify '4B pencil equivalence'

## Prompt Pack

## Comparison

| model | score | bestFor | limitation |
|---|---|---|---|
| HiDream I1 | 9/10 | Expressive/artistic sketches | Weak text legibility |
| FLUX.2 Pro | 7/10 | Photorealistic technical drawings | Over-smooths lines |
| GPT Image 1.5 | 6/10 | Instructional diagrams | Generic line quality |

## Frequently asked questions

### Can HiDream I1 create colored pencil sketches?

Limited capability - it focuses on graphite grayscale. For color, use GPT Image 1.5 with 'colored pencil' specification (18 credits).

### How to fix overly dark shading in sketches?

Add 'soft 2H pencil pressure' or 'light preliminary sketching marks' to prompts; reduce contrast in post-processing.

### Does HiDream I1 support image-to-sketch conversion?

Yes via Kontext Pro (12 credits) - upload photo with 'convert to academic pencil study with visible construction lines'.
