Design a whimsical digital illustration showcasing a close-up of a tropical flower, specifically a bird of paradise, surrounded by lush green foliage. Use a close-up perspective to highlight the flower's intricate details and vibrant colors, incorporating a mix of oranges, yellows, and blues to create a striking visual. Include small, playful bees buzzing around the flower, ensuring their wings glisten in the light to suggest movement and liveliness. The background should feature a soft gradient of blues and greens, enhancing the cheerful mood of the piece. Utilize bright, natural lighting to illuminate the flower and foliage, inviting viewers to appreciate the beauty of nature. In post-production, enhance the vibrancy of the colors, add subtle textures to the flower and foliage, and apply a soft focus effect to the background to create a sense of wonder and whimsy.
