Haha, nice one.

the bluish tint on the highlights feels a bit garish (perhaps go for a very light gray or beige if you want to avoid white?), but the rest of this is very strong and well-made

Not sure about the cyan, but at the same time I feel it is really subtle and used very well.  I'd like some subtle cyan on the right side of the flag bottom too

I know nothing about their culture except sausage and beer. But I really hope this wins the challenge.

Auf ein dunkles Grau-Blau hab ich gewartet. Bietet sich so gut an bei dem Schwarz Rot Gold.

Großartig!
