Examples
Create a beautiful travel lifestyle image of a woman in a light linen dress standing on a sunlit Mediterranean terrace. The background includes blue sea, white coastal houses, flowering bougainvillea, terracotta steps, and warm afternoon light. Use a soft travel-magazine aesthetic, natural colors, realistic facial and clothing details, and a balanced composition that feels bright, graceful, and shareable.
Keep the same woman’s face, hairstyle, expression, pose, and clothing, but replace the plain studio background with a beautiful Mediterranean seaside terrace. Add blue ocean water, white coastal buildings, soft flowers, warm sunlight, and a refined travel-lifestyle atmosphere. Preserve the subject’s identity clearly and make the final image feel elegant, bright, and natural.
Made with reference media
Create a charming editorial illustration of an outdoor breakfast table under a lemon tree. Include croissants, honey, tea, fresh fruit, wildflowers, ceramic plates, linen napkins, and soft morning sunlight. Use warm hand-painted textures, tasteful color harmony, and a polished storybook-meets-lifestyle-magazine style. The composition should feel cozy, beautiful, and visually refined.
