私（わ）はアニメの大ファンなのです

私（わ）は日本語を（セして義に）専攻して学（ぶしでないです）んでいません。ただアニメを見（る丈で）て、理解した日本語をしゃべ（でける）ってるだけです。日本の方（だ）たちとの対話を楽しみ（です）にしています。今後（を）もよろしくお願いします。ちなみに、（だすくの）大好きなアニメ（わ）はOPです。

I love Japanese animations.(I am great fan of Japanese animations.)

I don't major in Japanese in my school. I just speak Japanese which I understood from animation.

I am looking forward to talk to Japanese. Thank you in future.

By the way, My favorite animation is OP.

is it right?

especially, I couldn't understand "セして義に" and" 見る丈で", because they are not japanese words or don't have meaning.

p.s. i can't not read and write japanese,only speaking and listening.This passage was typed with my memory of Japanese pronunciation ，i am a Japanese illiterate，so please correct my writing in English
