What is the best way to describe the theme?

almost like you have a Hawaiian party.

then your theme would be Hawaiian.

Explanation:

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 .
