渴望的彩色铅笔情侣

Create a delicate colored-pencil artwork on off-white textured paper titled {argument name="artwork title" default="Longing"}. Show an intimate seated couple in a quiet, melancholic pose: a young woman in the foreground sits curled up in profile facing left, knees drawn to her chest, arms wrapped low around her legs, head bowed with a sad introspective expression. She has {argument name="woman hair color" default="dark brown"} messy hair tied in a loose bun with wispy strands around her face, warm natural skin tones, and wears a pale gray spaghetti-strap slip dress or camisole dress. Behind her, a young man embraces her from the back, leaning his face close to her shoulder/neck as if comforting or missing her; render him as a translucent memory or ghost-like presence using only pale blue pencil lines and light blue shading, with short tousled hair and a loose T-shirt. His arms wrap around her waist and legs, one forearm visible across the lower front. Composition is vertical portrait, the figures centered slightly low with large empty white space above, no background objects, no text. Style should look handmade, soft, unfinished, and emotional: visible layered pencil strokes, sketchy construction lines, fine cross-hatching, subtle eraser marks, fragile outlines, muted colors, realistic anatomy but not photorealistic, gentle paper grain, airy negative space, tender sorrowful mood. Use exactly two human figures: 1 fully colored woman and 1 blue line-art man; avoid extra people, hard digital edges, heavy ink outlines, glossy rendering, or dramatic background.
