21Show, don't explain

The fastest way to get what you want is to show an example.

Want the same tone of writing - give it a piece of writing you like. Want the same design - give it a screenshot. Want the same answer format - write out what the result should look like.

This works far better than adjectives. "Make it modern" is noise; everyone's modern is different. A screenshot of a site you like is something concrete to work from.

On images specifically: nearly every AI can see them now. You can drop in a screenshot of your own page and ask "why does this look wrong here" and get a real answer. Plenty of people don't know this and describe the problem in words, painfully.

The reverse works too. Show it something you dislike and say "not like this". Sometimes that explains the task better than ten examples of what you do want.
