I don't think think these images have anything in common with Leibovitz's work. I'm really very puzzled by that comparison.

As I said, a better point of reference would be some of Justine Kurland's work, which is also created in a similar way and which explores many of the same themes. If you spend a little bit of time with these images (maybe pause the video and watch in HD) you'll see a lot of details playing out, many of them employing all kinds of ideas (incl., occasionally, a sense of humour, too).
