Abstract line drawing of a symmetrical spaceship concept

Sketch of an abstract spaceship. Black linear drawing on a white background. The central shape is composed of curved and wavy lines, resembling a complex, symmetrical structure. The shape lacks a realistic representation of a familiar object. The composition is centered and emphasizes the abstract form. The perspective is frontal, and the lines are defined with varying strokes of black. The atmosphere is neutral, focused on the representation of lines and shapes. Notes and marks on the paper suggest design stages or observations of the sketches. The colors are monochrome, with black and white contrast.
