Which idea fits with which format?

In the previous crit session, the ideas that people mentioned/liked was the preserved Earth in the jar, the hanging ornament/bauble, the multiple hands holding up the earth as it adds the feeling of unity as well as preservation of the Earth and the ideas where the powerful/significant landmarks/buildings and people that exist/existed on Earth are made to look small to show its insignificance in this vast universe. Because people liked these ideas, I decided to develop them further and put them in different formats to see which one would work best with which format:-

Here I played around with how different shaped jars would affect the composition of the square format.

With the hanging ornaments/bauble idea, it was suggested that I added some perspective to it. I decided to make the Earth smaller than everything else to show how small it really is in the vastness of the universe. I then decided to make the Earth hang among the other planets, again, to show how small it is.

I felt that the idea with the tiny landmarks only worked well with the portrait format so I changed the idea slightly. The idea above shows a tiny house (planet Earth) in amongst big and tall skyscrapers (the other planets) to illustrate how our planet is really insignificant and vulnerable and really something to preserve and cherish.
