I choose 1.
my concept is merhen and religious .
these people use bone and energy which simillar carchole, and they have lots of mineral and oil.
They like tree, animal and reading books. They like beeswas, and beeswas crafts but beeswas is expensive(they import to other planet).
this planet has light(slim) and fast transfer. and this planet famous to develop of wheel.
So I draw guns and nives, motived by fairy tale, and beauty.
and this planet doesn't have special army, but some of people protect their books and mineral. this weapon is for them and police.
And I draw Transportation device what they use.
It have to slim and fast, and beauty. but some of is heavy because they carry goods which import to other planet.
