My dearest fanny, i am writing what will not be of the smallest use to you. i am feeling differently every moment, & shall not be able to suggest a single thing that can assist your mind.—i could lament in one sentence & laugh in the next, but as to opinion or counsel i am sure none will [be] extracted worth having from this letter.
in this passage from “on making an agreeable marriage,” jane austen worries that

fanny will be insulted that austen is laughing at her

fanny will ignore her good advice

she herself feels differently with each passing moment

she has good advice to give fanny

you need need more details so we can understand what your asking us.

sensory details?

so i`m assuming you are writing something from a bats (the animal) point of view. if this is the case, you can use sights, sounds, feelings, and tastes.

and idk what you mean by domain, but all of the sensory details will depend on where the bat is.

a bat doesn't see color very well, so its surroundings will be dulled.

it can hear super well. so maybe it can hear the insects on the ground

feelings. you can imagine how a bat would feel from its perspective. it all depends on where it lives.

maybe it can taste the salt in the air, or smell water, or something. all of these details are completely dependent on where it is located.

hope this .
