Sometimes, the part of architecture in minecraft that makes something really stand out is not the environment around the build, but the detail in the construction itself. More detail in a building makes that building more eye-pleasing and interesting to look at. However, even extremely detailed buildings can look plain or flat. The reason for this is the wall of it is completely 2D. To make a building really pop, make a surface 3D instead. Not only does it make it more appealing, it adds better shape and form to a build.
Making a build 3D greatly improves how eye catching a build is and may even help it to win contests.
