工程草图企鹅解剖

An infographic-style technical illustration of a penguin, combining a realistic photograph or photoreal render of a penguin with technical annotation overlays.

The penguin remains clearly visible as the main subject on a pure white studio background.

Overlaid on top are black ink, hand-drawn technical annotations in an architectural / engineering sketch style:
– Key anatomical component labels (beak, flippers, skeleton, muscles, blubber, feathers, feet)
– Internal cutaway and partial exploded-view outlines showing bones and organs
– Measurements, dimensions, and scale markers (height, foot width, beak length)
– Material and functional callouts (insulating blubber layer, waterproof feathers)
– Arrows indicating airflow, heat exchange, movement, swimming force
– Simple schematic and sectional diagrams placed around the main figure

The title “Penguin Anatomy” is placed inside a hand-drawn technical annotation box in one corner.

Style is educational, museum exhibit / biology textbook / engineering manual aesthetic.

Linework is black only, precise but slightly hand-drawn, technical pen look.

Clean composition with balanced negative space, no clutter.

No colors at all — strictly white background with black lines and black text.

Ultra-crisp, high detail, social-feed optimized, square format.
