Very good for your age for sure. Typography is one of the hardest things to do and to do correctly. You have done an excellent job for someone who is only 13. There are a few things that people could bark about, but IMHO, it is excellent for someone your age with probably little to no experience. The only thing that really gets me is the "from the safe harbor" line. Although you handled it pretty well with the thicker font that pulls your eye to the next word (congrats) it is also not a normal way to read things and for a second there I got stuck. Just remember most people read from left to right, up to down and that is the "natural way" we read things. That being said you have already grabbed the eye and guided it with the thicker font, but because it is the ONLY line that is not read this way, it confuses the reader.
Great job none-the-less!
