I'm kind of surprised no one has said this yet:
A fundamental flaw with the design of that building is the placement of its four roofs. Each "section" of the building is two storeys tall, and thus equal, yet the southernmost red roof overlaps both blue ones, creating a distorted effect. As well, the northernmost red roof, I'm assuming was made with the intent that it was also to be two storeys tall. With its placement underneath both the blue roofs, and the red roof, it makes it seem skewed, and out of place.

As well, your door is missing the bottom tiles for its frame, and all of the brick tiles used for your building are identical, thus making evident (upon light inspection) tile errors for each of your walls. It seems as if you designed the building from a predefined objects point, without using any of the tiles individually from the tileset. Further evidence of this is that there are no "middle brick" tiles, for placement between two edges. There are only edge brick tiles.
