Sure, go ahead. Actually I did think a little about it, but apart from maybe the Star of David I don't have any ideas, and since we are an Islamic theocracy that doesn't really seem fitting either.
Edit: Woah, wait a minute! Can I have a pony on my flag?
Hm, okay then, see if you can depict the Star of David somewhere.
Woah, I suddenly got an idea: Split in the middle, left side blue, right side red. A green regular star in the middle of the left half, on the right side a white Star of David below a green half moon.
Using the crescent makes you related to DKVM and Constantinople, rather to the muslim community itself. Our holy symbol is the one you may see on the mid of the polished version of Noob's flag. You may use the crescent if you want, but then the symbolism will be tied to Constantinople rather then to the Ummah.
I'll start working on your flag as soon as I get the available time.
Here is my first attempt, tell me what you think about it, if something should change, what you like or dislike, and any addition, removal or substitution. Also if you want to move this discussion somewhere else (where you actually answer my posts, preferably ) too.
For the blue part of the flag, I suggest you add a boat and ripples of water below it, representing Sham's prowess on the seas with trade and naval ambitions.
It should be on the majlis group honestly, when I first learned that this was being discussed here i couldn't understand why.
