Looking for feedback on my first ever site! Tribute page

Hello, I’m looking for advice and feedback on my site, which can be found with this link: https://codepen.io/Jesse-Cusser/full/zEjdXz/

I’m highly self critical, and I know the site could be improved, I’ve only been coding for less than a week, so I’m eager for feedback, I’m hoping mainly for advice on my code, which could be cleaned up. If anyone could give me tips on any coding conventions I’ve accidentally broken, or just way’s I could do things with less code that would be awesome. Advice on my pages aesthetics, and font suggestions are always welcome. Thank you for your time.

Thank you so much for your feedback, incredibly helpful advice. Looking forward to applying it!
