they are mostly looking at large flat areas. this won't print. the sky is very noisy and it blotches when it's smaller. at the very least the sky must be smooth.
you'll want to smooth the sky in this as well
oh and you might want to add some paragraph breaks in the bio, it's kinda hard to read in a massive block.
anyway, the site doesn't want to see - noise, shifting blur, blocks, stretching, bad crops, etc. mostly your skies are effected here.
