I tried to take more screenshots but my clipboard was acting goofy so this is the only DW beta screenshot i got so far.
I kind of dislike the way that you exclude the physical map from the background when in political map mode (at least in previous versions). Divine Wind had a quite good political map view, and I hope that you didn't change it? I can't see it from this zoomed out screenshot...
The map graphics and all its views are just like vanilla. The terrain and province shapes are different in some places for TN.
