Okay, looking at the map of Europe, a few comments (besides the generic AWESOME MAP!!!)
There are three "German" (Austria and Luxembourg don't count, as neither of them is likely to try and form Germany) States, and all seem to republics, and both of the ones large enough to be seem to be Federal in nature. This begs the question, if they're both trying to unify Germany...what's the difference? and if you have two states with a similar ideology and both want to join each other, why don't they?
Also, the Bavarian State is the "South German Federation" While the Prussian state contains no such qualifier, wonder what that means.
And is an independent city state with an ideology that would be unfavorably compared to the plague by the rulers of the time, bordering a nationalist Federation that has excellent grounds for including said city-state in its Nation, really going to survive that long?
Moving West, Belgium must be terrified, with Nappy probably strongly considering a partition with the dutch. Or just annexing it, although that would bring an alliance of Austria-Hungary and Brittan and...does the German Federation consider itself a legal successor to Prussia? who rules it anyway?
Moving to Austria, the Flag indicates that there's no Duel Monarchy, which makes sense if France gained the Rhineland by intervening in the 6 weeks war. But then why is it still called Austria-Hungary?
Poland having the borders of the Duchy of Cracov, I somehow see this French being involved in this.
