Describing people's characters

I am going to talk about my friends Lucia, Agustina and Florencia. Lucía is very out-going and chatty because she's always talking and she never gets tired of people, she likes to interact with everyone. Agustina is very kind to her friends because we have really good times together, also she is easy-going because she doesn't care what people think about her, unlike Florencia who is really moody and shy because she is always mad at someone or something and she doesn't like talking to people very much.
