Energetic and Lively Anime Sketch

"A hand-drawn anime-style sketch capturing the vibrant energy of a cheerful boy. The dynamic rough lines and textured pencil strokes give the drawing an expressive and spontaneous feel. His wide, open-mouthed smile and sparkling eye create an atmosphere of joy and excitement. Colorful accents in the background enhance the lively effect, while the white backdrop ensures focus remains on the character's exuberant expression."
