Sheet rejection (city tileset)

[Hiynastrike]

I can see everything wrong with it. by the looks of it, it appears no effort was made, just the square tool with some windows thrown in. The windows are on the right track, they have some detail compared to the rest of the sheet. If you want this sheet accepted then you got to buckle down and make some detailed and believable tiles, because would Nintendo have Mario running across flat weirdly colored blocks that serve better as a debug hitbox detection and call it a city?
