Current Flag:
I think this is an okay flag, but it’s easily confusable with the flags of other nations, such as the Netherlands and, to an extent, the other Slavic nations. The coat of arms in the middle isn’t too memorable either. I really like the crown of arms on top of the seal. The symbol on the far left is one of the early coats of arms of Croatia, and the others represent the regions of Croatia.
My Redesign:
I basically made a banner of arms of that symbol I mentioned earlier. I can’t really find anything on its symbolism, but I’m fairly sure that the crescent represents the Ottoman Empire. The star could possibly represent Hope, but I don’t know.
