Modern educational logo and poster design centered on a glossy vibrant red rounded speech bubble with subtle soft drop shadow. At the top inside the red speech bubble is a small stylized Union Jack British flag emblem. Below the flag, the text is written in bold, clean, friendly white font: 'Cool' in a friendly rounded typography and 'English' in a clean neat sans-serif font (no 'Learn' or other text). A black graduation cap (academic mortarboard) with a golden yellow tassel sits tilted on the top-left corner of the speech bubble for a friendly academic look. Surrounding the central badge in a neat circular halo is a pattern of delicate, thin, light-grey line art icons representing London and Britain: double-decker bus, red phone booth, Big Ben / Elizabeth Tower, Tower Bridge, London Eye, black cab, red pillar post box, royal crown, Queen's guard in bearskin hat, teacup with steam, St. George cross shield. All line icons have uniform stroke weight and subtle low opacity creating an elegant background frame on a clean, light neutral backdrop. Flat vector graphic design aesthetic, perfectly balanced centered composition, 16:9 aspect ratio, high resolution, vector illustration style.
