Art style: Watercolor Storybook.
Full-length view, the entire figure visible from head to feet, standing upright, centered — a grand old storybook oak tree with a friendly living face. A broad, deeply furrowed brown trunk forms the body, with kindly crinkled eyes set in the bark, bushy eyebrows of moss, a wide warm smile curving across a knotty wooden mouth, and rosy cheeks like ripe acorns. Two thick gnarled branch-arms reach out with twig-fingers, one hand gently open as if explaining. A full, rounded crown of autumn leaves in gold, amber, russet and orange crowns his head, a few leaves drifting down. Gentle laugh-lines and an expression of wise good humor. His base is a wide spread of thick roots gripping a grassy forest floor scattered with fallen leaves and little acorns, soft golden autumn light behind him.
