浮遊する小惑星で禅庭を手入れする小さなドラゴン

A whimsical scene of a teacup-sized dragon meticulously tending a miniature zen garden on the surface of a floating asteroid. Tiny bonsai trees and raked sand create a serene landscape against the backdrop of a vast, star-filled void. The style is a charming, detailed concept art, with a playful, lighthearted tone that contrasts with the cosmic setting.
