Prompt Engineering for Midjourney: Tips and Best Practices for High-Quality AI Art

Core Principles of Midjourney Prompt Engineering

Prompt engineering is the art of crafting text instructions that guide Midjourney to generate high-quality, visually compelling AI art. Effective prompts are clear, concise, and rich in detail, allowing the AI to interpret your vision accurately.

Essential Prompt Components

A well-structured Midjourney prompt typically includes:

• Subject: The main focus of the image (e.g., “a regal Siamese cat with piercing blue eyes”).
• Style: The artistic or visual style (e.g., “in the style of Van Gogh’s Starry Night” or “cyberpunk anime aesthetic”).
• Medium: The technique or material (e.g., “oil painting,” “pencil sketch,” “3D render”).
• Context/Background: The setting or environment (e.g., “running in a snowy forest at dusk”).
• Modifiers: Additional details like color palette, lighting, mood, texture, and composition.

Frameworks for Structuring Prompts

Several frameworks can help you organise your prompts for optimal results:

Best Practices for High-Quality Output

• Be Specific and Concise: Use clear, descriptive language. Avoid ambiguity and overly long prompts—keep it under 40–60 words for best results.
• Use Descriptive Adjectives: Enhance your prompt with details about color, shape, size, texture, and mood.
• Reference Artistic Styles: Direct the AI by naming artists, art movements, or cinematic techniques (e.g., “cinematic lighting,” “depth-of-field”).
• Control Composition: Specify aspect ratio (--ar), style (--stylize), and version (--v) to fine-tune your output.
• Experiment and Iterate: Test different phrasings, adjust details, and use the --seed parameter to recreate or refine generations.
• Avoid Contradictions: Don’t mix conflicting ideas or styles in a single prompt, as this can confuse the AI and yield inconsistent results.
• Optimise for Processing: Overly complex prompts may cause Midjourney to drop details. Balance specificity with simplicity.

Advanced Techniques

• Reference Images: Use --oref to attach a reference image for style or composition guidance.
• Draft Mode: Generate quick concepts with --draft, then upscale your favourites.
• Negative Prompting: While not native to Midjourney, some users employ creative phrasing to exclude unwanted elements (e.g., “no people, no text”).
• Community Resources: Build a library of effective prompts and learn from the Midjourney community’s shared examples and style guides.

Common Mistakes to Avoid

• Being Too Vague: Lack of detail leads to generic or unpredictable images.
• Ignoring Version Differences: Always specify the Midjourney version (e.g., --v 6) to ensure consistent behaviour.
• Overloading the Prompt: Adding too many unrelated details can dilute the focus and confuse the AI.
• Using Conversational Language: Write in clear, structured phrases, not full sentences or stories.

Example Prompts

• Basic: “Colored pencil illustration, bright orange California poppies, close framing, soft daylight –v 7”.
• Advanced: “A cybernetic owl perched on a neon-lit rooftop, hyper-detailed, cinematic lighting, dusk, cyberpunk aesthetic –ar 16:9 –v 7 –stylize 100”.
• Emotion-Driven: “Melancholy, lone traveller walking through a misty bamboo forest, muted greens and greys, soft watercolor style –v 6”.
