"3D render of a dark brown-skinned arm holding a blue crayon over an open coloring book. The hand has a casual, relaxed grip on the crayon. The perspective is from slightly above, looking down at the scene. The coloring book page shows a partially colored design. Natural warm lighting highlights the skin tone and creates subtle shadows on the book page. Scattered crayons are visible at the edges of the frame. Photorealistic style with a focus on the hand detail and crayon texture. Close-up shot that fills the frame with the arm, hand, and immediate coloring area."
