Question

Illustrate in perspective, a composition with a CUP, SAUCER and a SPOON placed on a flat surface. The materials are: 
Cup: Rubber 
Saucer: Glass 
Spoon: Wood 
Instructions: 
The drawing needs to be done freehand using a blue pencil. 
Do not use any drawing instruments (no rulers, compasses, stencils, etc.). 
Evaluation Criteria: 
Composition and correctness of perspective 
Quality of surface representation through shading 
Quality of lines 
Correctness of relative proportions 
 

Hint:

When sketching freehand in perspective:
1. Start with the horizon line and a rough vanishing point to keep your composition grounded.
2. Block in simple shapes first (like cylinders for the cup, an ellipse for the saucer, and a narrow rectangle for the spoon).
For materials:
Rubber (cup): Use soft, matte shading with no highlights.
Glass (saucer): Show transparency with light cross-contours and overlapping lines.
Wood (spoon): Add gentle grain lines and subtle texture.

Answer 1

Reasoning
This drawing presents a still-life composition featuring a cup, saucer, and spoon. Through the use of accurate perspective, thoughtful placement, and careful rendering of material properties, the image successfully conveys the distinct textures and forms of rubber, glass, and wood. 
1. Overall Composition and Perspective 
Placement: The cup is centered on the saucer, while the spoon rests diagonally across the saucer, slightly overlapping both the saucer’s edge and the cup's rim. This creates a balanced yet dynamic composition. 
Perspective: The slightly elevated viewpoint allows the viewer to see into the cup, observe the saucer’s curvature, and perceive the spoon’s shape. The ellipses for the cup’s rim, base, and saucer are correctly rendered, implying depth and correct vanishing points. 
Light Source: A single strong light source, coming from the upper left, casts consistent shadows to the right and slightly behind the objects. This unified lighting enhances the realism of the composition. 
2. Material Depiction 
A. Cup – Rubber 
Soft Shading: The lack of sharp highlights and high-contrast shading indicates a surface that diffuses light—consistent with rubber. 
Matte Finish: There are no bright specular highlights; instead, the highlights are soft and broad, implying a satin or matte surface. 
Subtle Texture: A faint graininess in the shading may suggest the slightly tactile quality of rubber. 
Form Definition: Despite the matte finish, the cup’s cylindrical shape and gentle curvature are clearly defined by careful tonal gradients. 
B. Saucer – Glass 
Transparency/Translucency: The flat surface beneath is faintly visible through the saucer’s base, especially in areas where the spoon’s shadow interacts with the transparency. 
Reflections and Highlights: 
A subtle highlight along the saucer’s rim indicates ambient light reflection. 
Slight value shifts within the saucer suggest internal reflections and refractions characteristic of glass. 

Cast Shadow: The saucer casts a light, diffused shadow, and the spoon’s shadow passes visibly underneath, reinforcing its transparent nature. 
Glossy Surface: The smooth, even shading and slight reflections suggest a polished glass surface. 
C. Spoon – Wood 
Wood Grain: Fine parallel lines and tonal variations follow the spoon’s contour, clearly suggesting wood grain and texture. 
Matte/Satin Finish: Like the cup, the spoon lacks sharp highlights, suggesting an absorbent, matte surface. 
Warm Tones (Implied): Though monochrome, the use of mid-tones and subtle textures implies warmth and the organic nature of wood. 
Form Definition: The shading effectively conveys the spoon’s concave bowl, tapered handle, and ergonomic form. 
D. Shadows 
Cast Shadows: All shadows are consistent with the identified light source, grounding the objects realistically on the surface. 
Reflected Light in Shadows: Gentle reflected light within the shadows, especially beneath the spoon and cup, prevents the shadows from appearing flat and enhances depth and realism. 
Conclusion
The drawing skillfully utilizes perspective, lighting, and shading to distinguish the materials—rubber, glass, and wood—through appropriate texture and tone. The interplay of light and form results in a believable and aesthetically coherent composition.
