Anime Chalkboard Character Formula

Design concept: single-page anime illustration with an information-dense classroom chalkboard. Layout & composition: vertical 2:3 portrait framing, chalkboard fills the background, character occupies the right half from head to thighs, writing fills the left half, warm classroom sunlight and gentle shadows. Visual style: bright polished Japanese anime key visual, clean line art, soft watercolor-like shading, warm sunlight from the left, high detail, cheerful official-character-analysis parody. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
