영어 발표문 적었는데 문법이나 내용 이상한지 봐주세요

여러 가지 부분에서 작은 수정이 필요합니다. 여기서 잘못된 문법 및 내용을 수정해 보겠습니다:

1. "Voldemort, whose face has regrown on the back of Quirrell's head, is revealed to be the professor's secret master"에서 "whose face has regrown on the back of Quirrell's head"를 설명하는 부가적인 절이니까 괜찮습니다. "truth has been so shocking" 역시 현재완료 시제를 사용하여 문제 없이 사용되었습니다.

2. "There're more important things. Friendship and bravery"에서 "There're" 대신 "There are"를 사용하는 것이 더 자연스럽습니다.

3. "The CGs used in the movie were very natural and good."에서 "CGs"를 설명할 때 좀 더 구체적인 용어를 사용하는 것이 좋습니다. "The computer-generated imagery (CGI) used in the movie was very natural and impressive."로 수정해 보겠습니다.

아래 수정된 내용입니다.

"I would like to tell you about Harry Potter and the Philosopher's Stone. This movie is set in the United Kingdom in 1991. The main character, Harry James Potter, enters Hogwarts School. My favorite scene is where Voldemort, whose face has regrown on the back of Quirrell's head, is revealed to be the professor's secret master because it looked scary and the truth has been so shocking. My favorite line is Hermione's 'There are more important things. Friendship and bravery' line because her line was to support Harry, and I was moved by that. The computer-generated imagery (CGI) used in the movie was very natural and impressive. The movie is full of tension, and the story is interesting. I give Harry Potter and the Philosopher's Stone five stars. Go and watch it."
