For some reason that static grass looks a lot better in the close up shots that have been posted. The green just looks a little too... I don't know... transparent?
The texture is definitely superior to ground foam, but I'm still not sure about the outcome in these views... Maybe its the flash that's washing it out.
Just the same, it's good looking group of modules. And good thing there's a carnival scene... wouldn't be N track without a Carnival scene!
