In short: The key visual is the parent. Get it right and the rest follows.
A key visual is your message and image resolved into one layout. It is the piece everything else is derived from, which is why it is worth more attention than any single format.
Your design kit decides how it is built, so a good kit here is what makes the output look designed rather than assembled.
Combine copy and image
Protaigé lays out your hero copy and hero image using your design kit, so type, colour and spacing are already yours.
Judge it as the parent, not as one asset
Ask whether it will hold up cropped to a square, a story and a banner, because it will have to.
Adjust before you scale
Changes are cheap now and expensive once a full kit has been generated from it.
Once the key visual is right, scaling it into a full campaign kit is the easy part.
