Build from light chalk on a darker support. Increase pale mark density across lit planes; leave connected shadow areas largely undrawn. Keep soft powdery volume and a few clear accents. Resemblance sits in big shapes: silhouette, pose, lit planes; below fingertip scale everything is pale chalk on dark support. Translate colors to faithful relative values. Eyes and nose are chalk marks with one chalk highlight. Light builds purely from pale mark density on the darker support, strands read as chalk runs and eye shine stays powdery. A tall scene of a polar bear in a close-up portrait, thick cream-white fur dusted with frost, dark nose and calm dark eyes, an icy blue arctic haze behind; no people, visible chalk deposits build illuminated planes from a darker blue-grey support, the shadows left as the ground. No readable text, lettering, signs or logos anywhere; the picture fills the whole frame edge to edge, painted right to the borders with no blank margin, no checkerboard or transparency pattern.
Palette: chalk white on slate blue; cold, calm.
