Alright, I figure it's time I get real flag for myself.
The regular flag should have a dark green background (if possible, the exact same shade as the background on
cantr.net) with the twelve animals of the Cantrian Zodiac in black arranged in a circle, in the following order starting at twelve-o-clock and proceeding clockwise: Dragon (eastern style, five clawed), Phoenix, Ox, Snake, Dog, Rabbit, Rat, Pig, Monkey, Ram, Horse, Tiger (so the Tiger and Phoenix will both be next to the dragon).
The Military Flag is dark green with a Dragon, Phoenix, and Tiger on it, forming a triangle with the Dragon at the top.
The Naval Jack has only the Dragon on it, coiled up like a snake (be sure to make the arms clearly visible, else it may be confused with an actual snake).
The Air Force Roundel is green with a Dragon head on it.
If any or all of these are too complex, tell me and I'll think of something else.
