So much do I want to avoid messing up the perspective on a background, I created a 3D model of Ikki's apartment in Sketchup. All the backgrounds in Ikki's apartment are taken from screen-grabs of this model.
So to show you around: Walking in through the door, there's the kitchen on the right, which leads into the living room. A door connects the living room to Ikki's bedroom. From his bedroom, one door leads to his bathroom, the other leads to a laundry room/walk-in closet. (Which I will never furnish because I'm not planning any scenes in there.) Let me know if you guys are interested in seeing any close-ups!
