1. artifacts/base.png: the base character, A friendly boxy robot with a rounded square head, big round glowing eyes, a smooth domed top with no antenna, riveted metal panels, painted in teal and silver, Creator's note for this redraw, follow it: Fix: smaller head with more shoulders and upper chest showing: the neck meets the shoulders at about y=740.. body and head turned about 15 degrees so the face points slightly to the viewer's right, eyes still looking at the viewer, both eyes fully visible; framed head and shoulders: the top of the head near y=210, the neck meeting the shoulders near y=740, both shoulders and the upper chest in the picture and running off the bottom edge; the arms are down and out of view, nothing in front of the chest; extra detail from the creator: looking at the viewer with a cheerful, curious expression, ON THIS TEMPLATE: crown (top of the head) at y=210, eye line at y=425, chin at y=665, narrowest point of the neck at y=700, head 340px wide at the cheekbones centred on x=500, bare shoulders running off the bottom edge about 880px wide.

Natural proportions for what it is: a human head or skull is about 1.3x taller than wide with a domed cranium and a jaw that narrows, eyes near the vertical midpoint of the head; never squashed or oval.

Transparent background; eyes open; a simple neutral closed mouth drawn on the base, matching the style (there is no separate mouth layer in this collection); no hat or headwear (hats are a separate layer); no glasses or eyewear (a separate layer); NO CLOTHING AT ALL: bare neck and shoulders, no collar, no scarf, no coat, no shirt (clothing is a separate layer drawn on top, and anything on the base shows through behind it).
