I'm world-building for a story set in an alternate 1940's Europe, and I've now reached a point where I need to come up with a flag for the main country. After hours and hours of meddling with different shapes and styles, reading ideas by vexillologists (yeah, it's a thing), I've narrowed it down to four variations! Which one do you like most? Which one's most realistic? I'm trying to make the flag iconic without being too similar to a real country. If it has a white symbol in the middle, don't fixate too much on that because it's mostly just a placeholder. There would be some sort of insignia in the finished version.
