Design an elegant pattern featuring delicate white flowers and roses on a soft dusty blue background, reminiscent of the classic toile de jouy style for wallpaper or textile design. Ensure that all elements are in an engraved or hand drawn style and symmetrical in composition to create a harmonious seamless effect. Emphasize intricate details with subtle shading techniques and use a monochromatic color palette for contrast against the light colored backdrop. --tile --ar 8:11 --style raw
