So....its basically like "The Pitt" from fallout 3 except with a little New Vegas thrown in..and...More Terrifying. XD (damn Pinkie rollercoaster)
Its basically how I imagined it: A giant wall protecting the city, the pinkie balloons (though I imagined them more Broken down and Rusty looking) and all the ruins outside the wall (I even noticed you put the little tiny steel ranger logo at the bottom right! Nice!)
All and all a great location and someplace that seems like my type of local to visit in a fallout like world! Death behind every corner, loot yet un-looted and the Rusty, Creepy industrial Vibe! Never stop dude
I can see Red-Eye in one of those Pinkie balloons, shouting "Weeee!" as he rides in them.
