Art style: Watercolor.
A dark walnut bookshelf in a dimly lit study, where a thick layer of grey dust coats a stack of books on leadership and strategy. A single shaft of weak, pale light from a side window illuminates the floating dust motes in the air. The atmosphere is neglected, quiet, and melancholic. Dominant colors are deep brown, charcoal grey, and pale yellow.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Watercolor" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Watercolor". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Watercolor" idiom, not in any other medium.
