Even though, the technically "correct" way to render architecture is to have all the verticals vertical, you can often conceive more energetic renderings by ignoring these conventions and rendering from a low or high point of view. The key is to avoid looking up or down at a slight angle, as this will look like a blunder, and instead go for a really climactic perspective.
Rendering from low down and looking up at a building really emphasizes its height, so it’s a great technique for rendering office blocks and other tall buildings. Look for point of view that will permit you to render the building at an extreme angle for an energetic composition (again this needs to be extreme enough to look deliberate), or strive for a symmetrical image.
