瞌睡小龙睡前绘本

一幅儿童绘本场景，一只圆滚滚的绿色小龙蜷缩在铺满柔软苔藓和发光水晶的温馨洞穴巢里，打着哈欠，一只小萤火虫为他掖好叶子被。柔和蜡笔水彩风格，温暖夜光，圆润柔和的形状，粉彩配色带惬意阴影。一个标题写着「就连小龙也需要休息。」宁静温柔梦幻的睡前故事氛围，宽幅柔和构图。

A kids' picture-book scene of a tiny round green dragon curling up in a cozy cave nest lined with soft moss and glowing crystals, yawning as a little firefly tucks a leaf-blanket over him. Soft crayon-and-watercolor style, warm nighttime glow, rounded gentle shapes, pastel palette with cozy shadows. A caption reads 'Even little dragons need their rest.' Peaceful, tender, and dreamy bedtime-story mood, wide soft composition.
