A bold city bus illustration in flat editorial style: a bright mustard-yellow city bus viewed from a three-quarter front angle, moving diagonally across the frame from lower-left to upper-right. The bus has clean geometric windows, a dark charcoal windshield, and brick-red accent stripes. Behind it, simplified urban buildings in muted grey-blue create depth without competing for attention. A few stylized clouds in warm white drift above. The style is reminiscent of contemporary editorial illustration, flat color blocks with confident outlines, no gradients. The bus casts a sharp directional shadow suggesting strong afternoon sun from the right. Intentional, designerly composition with strong diagonal energy. Distinctive flat illustration style with intentional geometric character, not stock-illustration look. No text, no watermark.
