Prompt Pitfalls

Leaving things out of your prompt. If you never specify what color hair you want, you may get very random results. Likewise, leaving things out of your negative prompts will also leave those options open for the AI

Using Terms in your Prompt the AI does not know. Never assume that the AI knows that one obscure character from your favorite anime, test and see. Sometimes context clues can help too. Specify the clothing.

AI cannot count. So writing 3 fingers is very likely not getting you 3 fingers.

AI might ignore negative terms in the positive prompts. Writing "A house without trees" will likely give you a house and trees.
