《歌ってみた》 『Kei』Only You

I worked on this for only 10 minutes so please excuse the crappy-ness of the singing. This video was basically made when I had an urge to sing it :) I would like to know what you think :) Also, I graduated middle school!!!
-Questions-
1) What did you think of my singing?
2) Who did I sounded like the most?
3) What were my highlights?
4) What were the downsides?
