Hey my friend!
Those are wonderful. I can only acknowledge how patient you are, I would have gone for stickers again, but you have loads of free time now you're retired, don't you? 😊
The rose is a very common pattern in English heraldry. Actually, when you see a five petal rose in a coat-of-arms, you can almost be sure it's English. In France, lilies were favoured, of course!
Flowers are common as mons in Japan. Master Cheng could show you dozens, but I can recall at least one, the famous Tokugawa family mon, which represents three rose leaves in a circle.
