I can say from experience you will be taking a big risk of a plotless NRP, those always see allot of post, then dry up when people wonder about waiting for something to do/happen. 

That said, I might be interested in being apart of this, been awhile since I have been a player in a fantasy NRP. :K

Edit: Also, 70% of the info on that NS is super not necessary, I mean, Art and Music? That can just be absorbed into a culture section, and some of the other segments seem out of place for a middle age Nation Sheet.

Though, I would advise something along the lines of flaws, and strengths, you'd be surprised how much that helps in creating specializations, also helps keep people form creating prefect realms or all capable armies.
