and could you not make it so....um... i wanna say plain but i want to say empty at the same time...
anyways
may i suggest, making the walls have more features, weather this includes adding fake vines, or jsut making it brick, thats for you to decide
too much flat floor space, its good for walkways but its boring to look at flat grass, especially in blockland
add some more player-built trees, not jsut the cheap little pine you an make in one button
]also add some interior detail, even if it is cosmetic (as is my style) and you cant actually go inside the building, jsut make something visible from the windows
