It's nice idea, I love Harry potter movies! I will do that because I have a 3rd Book of Harry potter but I stopped reading it before.

どういたしまして。(your welcome) P.S. If your trying to increase your vocabulary and english proficincy read an english novel, I reccomend "Harry potter and the sorcer's stone" it is a good book to read and is will probally increase your vocabulary.

Thank you for correcting. I now "wanna" is the one of the slang. The reason why I use the word is now I try to learn English in conversation to improve speaking naturally for verbal communication in the UK. I'm using English every day but I feel even though I can make conversation in the business situation, but I often feel my English is lack of vocabulary about slang and words which are only used for speaking. Thank you for our advice and be a friend. よろしくおねがいします！:)

As you may or may not know "wanna" is slang that is not used in propper english, more often it is used in text. Another error I have detected would be the part that says "writing". That should be write, to get correct subject verb agreement. But all in all you did a good job, and note I didn't write this comment to dscourage you, but rather to help you. ( :
