Explainer Video App Promo Cover

[Format] Landscape 16:9 gig cover, flat vector illustration with clean cartoon figures and solid color blocks. Smooth edges, no texture, no watermark, no personal names. [Layout] The frame is split into three tall diagonal panels that slant slightly from top-left to bottom-right. The left panel shows an office interior, the center panel shows a living-room scene, and the right panel shows a smartphone screen with a figure beside it. A bold green background unifies the first two panels, while the right panel is mostly white behind the phone. The panels overlap with sharp diagonal edges, creating a dynamic comic-strip feel. No headline text is present; the visual scenes carry the cover. [Subject] Left: a cartoon man with black hair and round glasses, wearing a blue long-sleeve shirt and dark trousers, smiling and holding a smartphone up with both hands. Center: a cartoon man with dark hair and glasses, wearing a blue t-shirt and dark pants, sitting on a red armchair holding a tablet. Right: a cartoon woman with brown hair in a red shirt and grey pants, dancing with arms raised next to a giant white smartphone with a green play button on its screen. [Headline] none — typographic only [Badges] A large green circular play button with a white right-pointing triangle sits on the smartphone screen in the right panel, centered in the white phone bezel. [Mood] Bright greens, red accents, and clean whites give the cover an energetic, friendly, app-promo feel. The split-screen layout reads clearly at thumbnail size and suggests multiple use cases for explainer videos.
