I see a couple of things:
1. that Ingsoc graphic looks a lot like the one used in the John Hurt movie. Copyright issues, perhaps? Besides, where are the images for Neo-Bolshevism and Obliteration of Self?
2. you're put the ministries in some pretty random places, plus calling western australia "land of BB" is pretty weird. What about having an Airstrip One inset (since that's where all the action of the book takes place), with all four Ministries, each with some sort of different bonus?
3. I also think you have too many connections between the three large nations. It would be an interesting tweak if you had to go through the disputed zone to get from, say, oceania to eurasia. Obviously the rocket bombs (a nice touch, btw, tho they'll have to be placed more carefully as the map progresses) would still be able to bombard far-off lands.
