It looks good but i do hope that both or all Monarchist paths will alow you to core ALL and i do mean ALL of Austria Hungary(From Krakow to Silesia, to Vojvodina Bosna and Venice...) and yeah can you bump that recrutable pop. for Otto up to at least 1.00% Since let's say he starts with 0.50% then when Austria become a kingdom to 1.00% and when he become an Empire let's say 1.50%?
Also why Kingdom of Austria? SInce historically that never really exited..(Nvm i have seen that you changed that

)
Other than these things It does look really good!
