Color: The color palettes are monochromatic, primarily using shades of gray (from light gray to black). This creates a sense of classic simplicity and emphasizes the linework and texture of the sketches. The absence of color adds to the handcrafted and slightly raw feel.
Lighting: The lighting is often implied through the linework and shading, with variations in line weight and density creating the illusion of light and shadow. The light source may be ambiguous or suggested through the direction of the lines and the placement of highlights and shadows.
Design Technique: The styles emulate the aesthetic of pencil sketches, with visible linework, hatched shading, and a blend of realism and stylized elements. The characters and objects are often depicted with dynamic poses and expressive features, conveying a sense of movement and energy. There's often a sense of spontaneity and immediacy to the sketches, as if they were drawn quickly and with a sense of passion. The styles convey a sense of handcrafted artistry, dynamic movement, classic yet slightly rough aesthetic, and a blend of realism and stylized elements.

Illustrations for Books, Comics, or Graphic Novels that Embrace a Sketchy or Hand-Drawn Aesthetic: The styles are perfect for creating visual narratives that have a raw, energetic, and slightly unfinished feel. The visible linework and hatched shading can add a sense of immediacy and authenticity to the storytelling.
