Mistake 1: Vague Prompting

Problem: Users type vague prompts like "beautiful landscape" expecting the AI to read their mind.
The Fix: Be specific and structured:

[@portabletext/react] Unknown block type "tableBlock", specify a component for it in the `components.types` prop

Mistake 2: Ignoring Composition Fundamentals

Problem: Focus on subject but neglect how elements are arranged.
The Fix: Direct composition explicitly:

  • Specify framing (close-up, wide shot, bird's eye view)
  • Apply rule of thirds
  • Include foreground, midground, background
  • Define focal point location

Mistake 3: Style Soup (The "Everything Bagel" Effect)

Problem: Users throw multiple artist names into prompts hoping for a magical hybrid.
The Fix: Focus on ONE primary style reference.

Mistake 4: Neglecting Technical Specifications

Problem: Focus on creative elements but overlook technical requirements.
The Fix: Include technical specifications:

  3. Adjust one major aspect per iteration
  4. Document successful prompts

  4. Include technical specifications for usable results
  5. Embrace iteration - it's a collaborative process
