Bản phác thảo mực chưa hoàn thành trên sổ tay

A photorealistic ink sketch of the subject from the reference photo, rendered in [violet and white ink] with fine cross-hatching on a [lightly textured notebook background]. A right hand holds a drawing pen over the paper, captured mid-action in an unfinished sketch. Minimalist brick-textured wall in the backdrop. Bright natural lighting, soft paper cast shadows, and a clean minimalist composition.
