Tip 2: Experimenting
The above example also demonstrates a second technique - experimenting.
When you get unexpected results, don't panic. Analyze the issues, then systematically adjust the prompts. Be patient. In the prompt above, there's one part I'm not sure you noticed - the "stock photo" at the beginning. What happens if you remove those words?

The results still meet the requirements, and the number of fingers is correct too. This shows "stock photo" doesn't have a big impact on the model.
