Create a minimalist illustrated book cover for a hardcover photo book, vertical format (21 x 29 cm). Concept: a personal “year in review”, celebrating turning 30 years old. The illustration should feel calm, mature, reflective and optimistic. Visual style: clean flat illustration, modern editorial design, inspired by contemporary travel posters and minimal vector art. Composition: a central abstract scene that subtly combines travel and memories from one year. Use simplified, symbolic elements inspired by Brazil, Guatemala and Colombia (Cartagena, Boyacá, Cali), without realistic landmarks and without clutter — everything should feel unified and understated. Color palette: soft blues, warm earth tones, muted greens; elegant and harmonious, not saturated. Use plenty of negative space. Leave clear empty space at the top for later typography (title and year), but do NOT include any text in the image. No faces, no people, no photorealism. No gradients, no heavy shadows, no textures. The final result should look timeless, refined and personal — suitable for the cover of a high-quality photo book summarizing a meaningful year of life and travel. See more
