Black and white sketch diary style, mixed media of charcoal and ink. Messy short hair and square glasses define the image of an intellectual, with thick eyebrows and thin eyes showing a blank expression. The brushstrokes are swift and rough, with flying whites at the edges and smudges preserving the painting process, laid casually against a gray background. The changes in line thickness express volume, with hasty parts contrasting with key structures that are finely detailed. The unrefined sense of intimacy feels like casual sketches of street observations, full of the granularity of life and the spirit of contemporary youth.
