Fantasy digital painting, dusk lighting, warm golden window glow against cool blue-grey misty sky, painterly detail, cinematic atmosphere. A massive ancient oak tree serves as a multi-level treehouse village: several round wooden cabins with shingled conical roofs built into the trunk and branches, windows glowing warmly from within, connected by rope bridges and ornate spiral wooden staircases. A stone archway door with stone steps at the tree's base, moss-covered gnarled bark, thick roots, distant misty forest with more small glowing treehouses in the background, desaturated monochrome grey palette, intricate linework, storybook illustration style
