The divisions in the red symbol remind me of the Tigris and Euphrates, one from the North and one from the East, nearly meeting around Bagdad and both contributing to a nearly-singular green belt from there South to the Persian Gulf.
I'm not sure, but the Sunni, Shia, and Kurds may be distributed in a similar pattern, allthough not-at-all deliniated by the rivers.
Apparently an eight-pointed star is a powerful symbol in Islam, but exaggerating the points like in OP's flag is not something I've seen in that context.
I would second the idea that an Iraqi flag without green doesn't sit right. Its literally the only color in their current flag I could tell you the meaning of.
Every time I consider that my near-a-terrabyte may be a little excessive, I'll remember anon.
Then again, I keep videos to 720P or less, and convert gifs to video, so if anon's an HD and/or 3D/Vr maniac, I could easilly have more than them, measured in playback time.
