The look feels like a blend of vintage engraved portrait plates, steampunk concept art, retro sci-fi illustration, and antique technical fantasy artwork.Trigger Use <code>YFG-Mline</code> to help bring out the intended style more consistently.Prompting This LoRA responds best to short prompts. Simple subject-first prompts tend to work especially well, for example:<ul><li>“astronaut portrait”</li><li>“woman in hood”</li><li>“steam train”</li><li>“mechanical centipede”</li><li>“golden armored warrior”</li></ul>Let the LoRA do the stylistic heavy lifting.Strength All sample images were generated at:<ul><li>LoRA weight: 1.0</li><li>Guidance: 1.5</li><li>Sampler: <code>er_sde</code></li></ul>Since the sample set was built around 1.0, that is the best starting point.

For best results, keep prompts short, start at weight 1.0 / guidance 1.5 / er_sde, and let the model’s visual identity take over.
