Very nice Skals. That's more professional than your last set of pictures. my crits are to displace the paths so they are dipped downwards slightly giving it more of a 3D look than just painted on.
I would also maybe add more grass models scattered around the level. GO has some decent grass models, some for edges, others for just slapping in the middle.
Lastly it might be nice to have some vehicles or something to suggest how the teams got there in the first place. Oh yeah and I'm still thinking you should destroy those far away trees with something more detailed...but I think what's damaging it is also the distance. It's obvious where the map ends and you can easily make a 3D skybox to further extend the view and create the illusion of a bigger world.
edit, one last thing: In this pic:

In other words just raise some of the displacements where the buildings meet it to just break up the flatness. It could also be the scale of the grass but it looks quite big, I dunno if scaling will fuck up your alpha painting but it might help just lowering it a litle more.
