I want to know what I did incorrectly, for next time no repeat my mistakes thank you

Doesn’t load past splash screen on mobile

Thanks for feedback, but can this be the only problem, for reject?

It doesn’t look like it’s Loading right on desktop either (big images piled on top of each their) - these could def be a reason

Footer is pretty empty

Typographic hierarchy could be better
