Japanese Restaurant Promotional Poster

Using the provided reference image of the udon meal, turn it into a clean, print-ready Japanese restaurant promotional poster while keeping the food photo itself as the main hero image. Expand the composition vertically into a portrait flyer layout, add a light icy-blue seasonal background with subtle watercolor texture and faint wave motifs, and overlay decorative green maple leaves for an early-summer feel. Add 5 text elements in Japanese: a blue circular badge at the upper left reading "初夏のおすすめ", a large bold brush-calligraphy headline across the top in 2 lines reading "とり天" and "ざるうどん", a small red vertical seal near the headline reading "自慢のとり天", a tall translucent blue vertical copy block at the upper right reading "ひんやり、つるり。さっぱり、満たされる。", and a price block at the lower right reading "980円 税込" with a blue brushstroke banner below that says "大盛り無料！". Add a short 4-line Japanese body copy paragraph at the lower left describing the dish in a menu-poster style. Preserve the original meal arrangement and realistic photography, but enhance it slightly for advertising: brighter, more appetizing, crisp, and high contrast. Make the overall design look like a polished restaurant poster created from a casual food photo
