character: takamatsu_tomori, A monochrome half-body portrait shot from a front view of Tomori Takamatsu, presented as a black and white pencil sketch in a sketchbook style. Tomori, a girl with short messy hair and a timid, sensitive expression, is centered in the frame. She is wearing an oversized, comfortable hoodie with long sleeves that partially hide her hands; she carefully holds a small, ordinary stone in her palms, gazing at it with deep focus. The background is a plain, unfinished sketchbook page with rough lineart. The image features delicate sketch lines, detailed graphite hatching shading, and soft natural lighting that emphasizes an introspective, quiet atmosphere, maintaining a hand-drawn, semi-finished aesthetic.
