Well Done. Now is precise. Just it seems you confused the central and south bonus.
If you let me few other suggestions I think Ardeal(orange) and Partium(blue) would be ideal bonuses for Transylvania, and if you place city in Transylvania than Kolozsvár(purple) would be good historic and strategic center.
And also would be cool if two territories in Ardeal can represent the Szeklerland (Székelyföld) and Saxonland (Siebenbürgen). These are the blue and yellow regions in the eastern edge.
