Explain the best way to determine point of view

To figure out point of view (POV), look for the PRONOUNS.

First person: told FROM the narrator's/author's point of view: uses the pronoun "I"
Second person: told directly TO the reader: uses the pronouns "you/yours" (for what it's worth, this POV is rare.)
Third person: told as an observation ABOUT the characters: uses the pronouns "he/she/it/they/his/hers/its/theirs"

Is there more to this?
