For JW Marriott Seoul’s Christmas collaboration with KidsCan, I developed the visual concept and graphic system for JW Winter Forest, a seasonal pop-up designed for children and families. The experience was built around a story of animal friends gathering in a snowy forest, creating a warm and playful world that children could explore at their own pace. Hand-drawn characters, muted winter colors, and layered forest scenery formed a cohesive visual language that extended across posters, spatial graphics, printed materials, photo zones, and interactive games. By connecting storytelling with physical activities, the design transformed the hotel space into an inviting winter environment where children could play, discover, and create memories.
