Superb presentation! I like the natural tone and your sentence structures are almost perfect. Also, you deserve a separate thumbs up for the diverse vocabulary. There are two details I would like to point your attention to:

1) Double check the spelling of certain higher level keywords. For example"nobleman", not "novel man". In some cases, including this one, the whole meaning of the word will be different (novel means new)

2) Take care for the usage of "a, an, the". sometimes, you do not need to use this words, like in one of the last sentences about Sungkyungkwan (an enormous university)
