Looking good, Bookmarked and look forward to seshing it. Just from the pics I can tell the park itself lacks minor "realistic" details, no biggie though, just a personal preference of mine. I hear ya on the "to scale" issue too. Sometimes making things to scale makes it crappy to skate in game. The floor I would use some different textures here and there, I usually stagger the sidewalk components and stock plaza pads for flooring. Ad some support beams here and there for the ceiling also and patch up the walls like repairs were done within.

Park does look like you can flow around though which is what it's all about!! That as apposed to 1 - 2 push, do trick, then stop parks.
