I really like your approach of thinking of the aquascape as "balanced". I think this is a much better way of approaching reef aquascaping than being overly focused on what the rockwork looks like at initial setup.
I have always found reef tanks more difficult to aquascape than freshwater, planted tanks. I think this is in part due to the dynamic role of a hardscape/rockwork as the reef tank matures out.
In freshwater tanks, the hardscape is typically the visual focus and this doesn't change much as the tank matures. In new saltwater tanks, the rockwork is similarly the main point of visual focus. The corals in a new tank are typically too small to play an impactful role in aquascape; instead the corals compliment the hardscape.
As the corals grow out, they start covering up the rockwork and also start change the topography and balance of the aquascape. For example, Zoanthids and soft corals visually soften the hardscape, and branching corals can even completely change the profile of the hardscape. Coral coloration also changes the visual weight of the aquascape as well (i.e reds are more visually dominant and have more visual weight).
Due to this shift as reef tanks mature, successful aquascaping in a reef tank requires some foresight. You have to design the rockwork with enough room for corals to grow in, while also being mindful of how it will look when corals are grown in. You also have to carefully select of corals for their eventual shape and color, as this will dramatically affect the shape and balance of your aquascape.
Here's an example of how my aquascape has shift with time. This is my tank when I first set it up last December. As you can see, the rockwork dominates the aquascape and the corals play a complimentary role.
Here it is now, with the corals steadily growing in. The rockwork is barely visible anymore and has lost some of it's original profile/shape due to the corals. At this point the corals start playing the dominant role in the tank's aquascape and the rockwork starts playing on a supportive role.
