A minimalist flat illustration with a ceremonial greeting aesthetic based on the theme of [college entrance exam success]. Composition: - Top section: Generous negative white space for breathing room, with a delicate small-font signature and subtle seal marks in the upper-left corner. - Middle section: Sparse, elegant handwritten blessing phrases or slogans acting as an emotional anchor. - Lower section: Main focal area designed like a hybrid of a postal stamp and an admission ticket border, with uneven line weight and deckled hand-pressed edges. Details: - Inside the lower border, a large, coarsely textured thematic character or motif serves as a subtle background element. - A central symbolic icon rendered in clean vector lines and solid flat color blocks stands upright as the main focal subject. - Surrounding details include miniature icons, brief inscriptions, and circular stamp seals layered like annotations on a handmade gift card. Style & Color: - Paper craft and risograph aesthetic with fine paper fiber texture and slight screen-print misregistration. - High-brightness, clean off-white background with bold cultural accent colors for structural outlines and characters. - Bright, solemn, intimate, and pristine mood without heavy distressing or grunge.
