Value can express mood or form. Ideally, values must express both. Don t mix them on the palette. Rather, combine the hues on the painting itself. Don t be seduced by texture, which is superficial.
Form is synonymous with structure.
Texture is the superficial element in painting. The creative process is like riding a horse. The answer is not in your painting. Good drawing is the window to the soul. The best realists are the abstract artists.
