"Design a captivating template featuring an arrangement of hyper-realistic flowers, including delicate orchids, bold sunflowers, and lush greenery, thoughtfully clustered to one side of a bright white canvas. Utilize soft, natural lighting, preferably side lighting, to enhance the vibrant colors and intricate details of the petals, allowing them to pop against the minimalist background. The layout should leave significant creative space on the opposite side, facilitating easy integration of text or other design elements. Incorporate a shallow depth of field to draw attention to the floral arrangement while maintaining a serene and inviting atmosphere. Render the image in stunning 4K ultra-resolution to ensure every detail is crisp and visually engaging, radiating a sense of elegance and tranquility."
