Following a new tradition, the Springfield is named after another well known anime/manga character. She is about 150 studs long and designed to be an "open hull freighter" - similar to a flatbed truck.
The whole ships "cheats" to attain the 100 stud "SHIP" status with a frame that is reasonably flimsy. I also think the modular construction detracts from the ship's appearance (I mean, it's a cylinder slung under a stick). No sophisticated building techniques are used (I loved cramming all that stuff into the crew quarters, but it's still all Studs on Top), only a little SNOT is used around the engines and bow area. The only thing I'm really quite satisfied with are the engines, but since it is my first attempt at a large scale MOC, I think it's reasonable as a whole.
Build time was roughly a month, and absolute build time was around 30 or so hours.
