Tribute page feedback appreciated!

I’ve completed the tests that are required for me, so I guess the page is okay from a technical perspective(?).
Still, semantic HTML is confusing and I would like to know if I am using the correct elements.

Also, while I’ve tried my best, the page still looks a bit odd and I’m not sure what I can do to improve it from a design perspective.

Please let me know what you think about it! All feedback is welcome
