the influence of the force depends on the checkpoint, but here are approximate values.

0.2-0.8: Just a gloomy autumn city.

0.8-1.2: Stylized abandoned city.

1.2-1.8: Post-apocalyptic ruins with elements of mysticism.

1.8+: Increasingly fantastic horror.

0.8+: The background begins to dominate and the character takes up only part of the picture. So because of the size, you will have to use a face fix.

Different stylistic resources will primarily affect the character without much influence on the style of the city.

It is not always possible to get rid of people to create a bare landscape. You will have to use unique negative prompts by removing a specific element that gets into the frame.
