### Self-score vs judge, by axis

Best round v2, 0–10 per axis

agent self-scoreexternal judge

**Judge:** The pelican reads clearly, with a big orange throat pouch, white body, a wing reaching forward to the handlebars and orange legs with feet on the pedals; the neck is a thin, stiff stick and the head is small. The bicycle has spoked wheels, a red frame, handlebars and a crank, but there is no visible seat and the geometry is odd: the seat stay seems to run to the rear hub, and the down tube and pedal placement are confusing. The flat-shaded style is clean, with speed lines and a ground shadow.

### Score by round

Out of 40. Each round starts from the previous round's best SVG. Dashed line: the 28/40 pass threshold.
