Fans of Hetalia and anyone interested, I need help! Which one looks best?

So recently, I have been watching an anime called “Hetalia” and have been inspired by to make a fanfic where a new country s the Hetalia cast, the “Mars Colony”.

It is an American Colony that was originally just a bunch of scientist and Astronauts but soon they started establishing a civilization on Mars.

Flag Color and Symbol(s) explanation

Red, white, and blue are the American flag colors.

Orange represents Mars.

Yellow represents the sun (a hope that we will continue to make leaps and bounds to colonize/explore our solar system and unlock the secrets of the universe).

Black represents outer space.

Green represents life, plants, and the terraforming of Mars.

The white sun on FLAG1 represents our Sun :sun_with_face: .

The orange star :star2: on FLAG2 represents the Mars colony as the newest American Country.

The fifty small stars :star2: (twenty-five on each side) on the FLAG3 represents the fifty states of the USA. The big star in the middle represents the Mars colony as the newst addition to the USA's family.

The yellow sun on FLAG4 represents our Sun :sun_with_face: .

I will also be doing a related poll on what I should name the country.
