Writing Feedback / essay on describing a friend [3]

Hi, please have a look at my essay on describing a friend and give me some feedback!thanks!
I think that i am very lucky because i have a lot of friends. Among my best friends is Mai. She is 16 years old. we live in the same village . She is my neighbor and we are now classmates, so we have been friends for so long.

Mai is tall and slim. She has long black hair. she has got an oval face with big bright eyes, a high nose and a small mouth. Mai is very beautiful, especially when she smiles. She is helpful, caring and honest. When her friends have difficulties, she always tries her best to help them. although we nearly have the same tastes and interests, we have some different characters. I am sociable and enjoy telling jokes. Unlike me, Mai is quite reserved and likes peace and quietness in the library. But there is mutual trust and a perfect sympathy between us, so we are very close friends. Mai is one of the best students in my class but she is always modest. She is also responsible and careful. I like working with her. She tries her best to finish her work. I think as time goes by, our friendship will be deeper and deeper.
