One of the stated design goals with the existing design is to make them as generic as possible so as not to show favouritism towards a particular country. If you asked me for famous European figures to put on the notes, I’d probably name Beethoven, Curie and Da Vinci, but by including them you’re highlighting a Germany, France/Poland and Italy. The building designs are boring but that’s not necessarily a bad thing. The birds are cute, but I’d like to have seen broader nature themes: birds, fish, mammals and biomes would have been nice.
