[Nagoyankee]

Your Japanese is actually good. It sounds fairly natural as well.

Just a few pointers. I wouldn't call them corrections.

先生 > 教師（きょうし） or 教員（きょういん） You can address your teachers 先生 all you want. But you won't use the term to refer to someone's profession unless you're a small child.

テーブ ルテニス > 卓球（たっきゅう）

ないから　＞　ないので. 　から makes it sound too conversational.

One could make more changes if one had to. But judging from your use of kanji and grammar, further "changes" will probably be useless at this stage. I'd say you've done bloody good.
