This tag should be used when a macro character is large enough to make the landscape itself look small in comparison.

This tag should however not be used if the character is large enough for the landscape itself to not be discernable in the image as is often the case with giga sized characters. Or if there is a complete lack of landscapes.

The landscape tag is often relevant when the landscape_dwarfing tag is used, but not always since there might not be sufficient room left in the image to emphasis the landscape.

Similarly to the landscape tag there still needs to be landscape features visible in the image. Some green and blue splotches on the ground isn't a landscape. Same goes for views of whole planets. By the time mountains aren't visible use the giga tag instead.

Refrain from using the size_difference and extreme_size_difference tags when dealing with macros in general. Crowds are rarely detailed enough to be more than scenery. Bystanders are often specs of dust. Cities can be argued to have inhabitants, same for continents and planets, galaxies, universes and beyond. But don't misuse the size difference tags if there isn't multiple subjects/characters clearly visible in the image. With an obvious exception for images drawn from the crowd/bystander's perspective, since then they are often a subject of the image.
