Not really something I'd expect to be full - nice shot, though

I wasn't sure either, but it kinda shows there is still some places without humans around to fill it up with garbage, y'know.

This is definitely not empty but it is an amazing shot. Thousands of trees, clouds in the sky mountains in the background. The absence of humans doesn't make it empty.

what is expected to be there that is not there?

there is a person in your empty shot!
