Can somebody please check if the puntuaction and the use of adjetive clauses is correct? thanks?

My friend Kazuko sometimes helps me with my English writing. She was born in Japan, but she spent part of her childhood in America consequently; her English is really good. She is not like an American. Americans seems to be very direct. In contrast, Kazuko is very indirect. For example, she never tells me that I have made a mistake; instead, she points to a line and takes a deep breath. She also makes a small “tsss” sound or alternatively, she may say some part needs ‘special attention’. For her, anything is ever wrong; it is simply ‘no finished yet’; as a result, I have not only learned English from her, I have also learned how to be helpful and patient. Nevertheless, on this occasion, I think that she will have to take a few deep breaths, when she reads this. In other words, it is not finished yet.
