I made sentences

1. Blunt : she is a blunt person  correct!

-"thinking" is in present progressive tense here, so it needs the conjugated form of "to be." Also you need the preposition "about" here.

-singular countable nouns need articles "the [if we're talking about a specific one]" or "a/an [if we're not talking about a specific one]"

-to express that actions of "animals" or "an/the animal" are brisk, you'd say "animals have brisk actions" or "the/an animal has brisk actions"

-favorite needs to belong to someone, "his/hers/my/our/their etc"
