I made a mistake once I started making more detailed prompts and I see it repeated often. Something like:

["Main prompt by Greg Rutkowski:20", 
"other details", 
"more details", 
"modifier", 
"modifier",
"modifier:5",
"modifier:5",
"trending on artstation:7",
"blur:-1",
"depth of field:-1",
"dof:-1"]

This is great from the perspective of giving the program details to work with but from my experience each element in the array acts as a competing piece of input. Whereas commas in a single item in the array act as parts of a coherent thought. This means that (particularly when dealing with long, wordy prompts with lots of modifiers):

["a, b, c"] #Syntax A: acts as a single thought with 3 elements
["a", "b", "c"] #Syntax B: acts as 3 competing thoughts

If your prompt contains a lot of details that can potentially compete, this small difference quickly adds up:

<aside> 🧪 Syntax B Examples:

</aside>

<aside> 🧪 Syntax A Examples:

</aside>

• More Examples (Syntax B)

• More Examples (Syntax A)

3 elements with no unusual weighting seems to be the sweet spot, therefore I recommend this format:

**"primary subject prompt** (I like to think of this as the title of the piece) **by author and author and author** (In order by how much you want their style to influence the result) **,** **a much more detailed description of the piece with adjectives as if you were writing an image caption** (try to use and instead of commas to keep thoughts complete where appropriate)**",**

**"style prompt including modifiers, color scheme, etc. comma separated** (again in order of importance)",

"negative prompts and negative modifiers comma separated:-1"

• Here’s a more technical breakdown from the cheatsheet of why this effect occurs if you’re curious about the math of it (click to expand, emphasis mine)

And that’s it! After you do some testing if you absolutely need to you can add weighted lined, but I recommend you still group things of the same weight together as comma separated pieces of a single quoted array element.
