Pastel illustration of two smiling cartoon girls hugging amidst a border of flowers, with the book title "Once Upon a Flower".

Create a brand-new, original book cover illustration, painted as a single wide horizontal scene from left to right, like one continuous painting rather than separate panels. Aspect ratio close to 2:1 (final output 17.536 x 8.750 inches / 5261 x 2625 pixels at 300 DPI). Generate the image at the highest resolution and maximum level of detail the system allows — this artwork will be used for large-format professional printing, so image quality and sharpness matter a great deal. Style: soft, minimalist pastel illustration, gentle rounded shapes and colors. The whole picture is filled with a delicate border of large soft flowers (daisies, roses, tulips) in muted pastel tones running along the top and bottom edges of the entire image, plus down both the left and right outer edges, with a few loose petals drifting near the edges. On the right side of the picture: one or two little girls with simple bob haircuts stand among the flowers, joyfully hugging or leaning against bold, richly colored flowers. Above them, in the center of this right side, there is an open horizontal area with soft blurred flower petals drifting gently into its edges — reserved for a book title and subtitle. Render the title "Once Upon a Flower" in large elegant lettering, with the subtitle "A Whimsical Coloring Book of Adorable Girls and Their Blooming World" in smaller lettering beneath it, and the author name "Nadia Vera" in small lettering near the bottom of this open area.
