Whimsical imp portrait with vintage ink and pencil style

Hand-drawn ink-and-colored-pencil illustration of a small whimsical character in a vintage pin-up/retro comic sensibility: energetic cross-hatching and stippling, loose sketchy contour lines, warm sepia base with muted teal and coral accents, soft watercolor washes, pronounced chiaroscuro with glossy highlights, tactile paper grain and slight grainy tone. The figure in three-quarter view: fluffy orange hair, pointed ears, small green top hat, oversized green bow, orange-and-green striped jacket and vest, puffy knee-length breeches, green-and-white striped socks, buckled boots and curled tail. Playful doodle embellishments, intimate cozy atmosphere, minimal neutral background, warm nostalgic stylized portrait.
