>>707>>I had been learned playing the piano
これは時制どうなってるの??
どういう意図でhad been learned?
>>It became most exciting event
これは現在も続いてるんだから
It had becomeかIt isのほうがいいんじゃないかな。
全体的に雰囲気としては悪くないけどもうちょっと時制とか単語の使いまわしに気をつけたほうがいいかなー。
ちょっと直してみた。
I've learned playing the piano for a long time.
When I was in elementary school, I and my sister had a piano competition.
I was really nervous at that time, but my sister encouraged me.
Thanks to her, I could enjoy playing the piano, and we could play very well.
In addition, to be surprised, we got a first prize in the competition.
I was very excited.
Because of the happiness, tears dropped down naturally.
That's the most exciting experience I've ever had.
