This B1 poster was designed for “iGEM TSUKUBA,” a children’s event hosted by students from the University of Tsukuba and held at AEON MALL. While maintaining consistency with the client’s existing promotional visuals, I developed a friendly and approachable tone that would appeal to both children and adults and make the event feel easy to participate in. The layout was carefully structured with consideration for readability, visibility at B1 size, and natural eye flow, resulting in a bright, summery design.
