First, I messed up, and I would be stupid to think differently. Anyway...
I didn't really manage to communicate my intentions to my neighbours. In the north, because of an evident alliance E/F, I was hoping for German assistance, and Zmaj went for Sweden (I can even understand it, but why did you prefer to die against me in StP instead of defending against France? Was my claim on Sweden that unbearable?).
And then with France, when I supported Tyr - Tri he moved Tyr - Pie, and when I supported myself, obviously Tyr - Tri. Austria, like Germany, preferred to die instead of being defended by (my) Vienna at last (but why? Wasn't Turkey as guilty as me of your condition?)
And in the north... did England understand that I was at all cost trying to make him destroy my second fleet to build an army south (thus, for his own convenience, too)? No, but how should I have explained it to him?
And my mistakes throughout the game didn't really help... Sorry.
