The writing is pretty good as for the content of what you're trying to portray. I did enjoy it. There are several spelling errors I noticed along the way though. Mostly minor stuff like a "wiht" instead of "with". A more specific thing I will point out since you said English isn't your first language though. At one point you were writing about a writing instrument which Harvard was using. The word you're looking for there is "pen". A pen is a writing instrument, a pin is something different depending on context. I know words that are pronounced the same, but spelled differently make English confusing.

Thank you for the feedback!
Typos happen a lot. Where did you see this error with the writing instrument? Since Havard could have been writing with a pen, or talking into his "communicator pin" i.e. it could have been on purpose or at the very least, I would have hard time finding it by just searching for the word.

Looking back at it you probably did mean the pin you had written about earlier, but because it came right after talking about writing my brain tried to correct it to pen.

This does seem like he is using the communicator pin :D Understandable connection right after he was writing. Still thank you, I fixed one "wiht" so far, just putting it in the word search.
