Hand-drawn architectural concept sketch of a complex avant-garde sculpture. The structure features a central rectangular monolith supported by thick, organic, root-like buttresses that curve downward to a flat square base. A delicate, open-lattice geometric grid is visible through the hollowed center of the top section. The entire piece is rendered with heavy, expressive mixed-media textures: thick impasto palette knife strokes of cerulean blue, cadmium yellow, and deep magenta, overlaid with tattered, reflective 24k gold leaf flakes that catch the light. The style is a professional artist’s sketchbook study, using graphite pencil for fine structural lines, watercolor washes for the vibrant colors, and metallic ink for the gold accents. High-contrast lighting with soft charcoal cross-hatching to define depth and shadows. Natural cream paper background with slight grain and occasional stray paint splatters. Ver más
