Critique my Tribute Page to the Straw Hats

My Tribute to the Straw Hats

I need help recognising how I could improve my Tribute Page. I have made it as responsive and pretty as I could with some help.

Basically, what more can I do to improve it and what could I do better? I feel like it’s very easy to pass the tests from the CDN link but to actually output a quality page is much more sophisticated.
