Which is the best practical approach in advanced form study?

First establish the basic mass, then analyse the planes, and finally study the light–shadow relationship

The governing concept is structural progression: a complex form should be built from large, simple relationships toward smaller descriptive information. First, the artist observes or blocks in the basic mass so that size, proportion, and placement are stable. Next, the major planes are identified to explain how the object changes direction. Only then should light and shadow be organised according to a consistent light source. This sequence makes errors easier to find and prevents attractive details from hiding weak construction. Option A is correct. B begins with information that depends on an unbuilt structure, C removes the basis for coherent values, and D denies the three-dimensional nature of form.
