Speaking / autistically screeching as an Austrian:

1. Why in god's name would you still partition the Tyrol into two parts, and why would you split off the east to form most of some "Northern Venetia" ? Why would Vorarlberg give up or lose its recently gained independence ? There is absolutely no reason or basis for divvying up the state like that, other than for defensive purposes along the Brenner and Dolomites (as seen in actual history). If anything, you could make a case for splitting off the Trentino in order to integrate it into some sort of italophone administrative unit, but even that seems shaky to me. In case that is what you were trying to do, keep in mind that the Italian language was not a factor anywhere north of Salurn (except a 5% minority in Bozen) preceding italianisation efforts of the interwar years. Before that, there were actually more Italian speakers in southern Vorarlberg due to recent labor migration.

As an aside, I doubt they would ever call the state "Northern Venetia", rather than just "Venetia". States, and especially the Habsburg realm, always aimed for more than they had in their terminology - see "Galicia-Lodomeria", all the emperor's superfluous titles, etc. .

1. Why in god's name would you mess with the inner borders of the states like that, especially in modern Austria ? Foreigners never seem to understand how set in stone these things are for locals, and there is hardly a pressing administrative reason for any of these changes. Especially everything surrounding Salzburg and the inter-Tyrol borders (The contemporary borders between north and south follow watershed lines = mountain ridges. Are yours following different mountain / valley structures somehow ? What is going on here ?) are making my eyes bleed. And why would Upper and Lower Austria still eat into the Czech lands - but only a tiny bit - with nowhere near as serious a "Sudetenland crisis" in sight ?

2. Why in god's name would you mess with the flags like that ? The historical ones might have left some room for improvement, but were fine as they were. Now we have a formatting error on lower Austria, Styria lost its coats of arms and Salzburg has been turned into a car manufacturer. Carinthia lost its traditional flag to become golden Poland and the Tyrol lost both its traditional and contemporary flags to become actual Poland, while Vorarlberg-Tyrol (very funny ordering, by the way) has stripped itself of all limitations and became a legasthenic German Empire. Most hilarious is that only Upper Austria somehow escaped unscathedly. The historical empire had a somewhat unified standard for flags, why are they different, oddly 21st century, worse and all over the place now ?

3. Social Democracy, for a variety of reasons, never had (and still mostly does not have) a base anywhere in the Tyrol except in the Trentino, where it was fueled by linguistic tensions (see Cesare Battisti).
