One Open Umbrella · Radial Panel Construction

SUBJECT
One open blue umbrella with eight canopy panels, viewed from below. Its ribs meet at one central hub, and its shaft extends from that hub toward a curved handle.

COMPOSITION
Use a slightly oblique underside view on a plain warm-white background. Place the canopy across the upper two-thirds of the image, with the shaft descending toward the lower right and the entire handle visible.

STYLE GUIDE
1. Shape & line
Draw eight slender ribs radiating from the same visible hub to eight distinct rim tips. Bow each panel outward between neighboring ribs, and connect adjacent tips with shallow inward-curving scallops so the canopy reads as one continuous tensioned surface.

2. Color & light
Use a restrained blue palette with soft light arriving from the upper left of the image. Make the upper-left canopy panels lighter and the lower-right panels deeper blue, blending gently within each panel while preserving the darker rib boundaries.

3. Texture & material
Render the canopy as matte woven fabric with a faint, sparse grain and a few short creases extending inward from the rim tips. Give the exposed metal ribs and shaft narrow pale highlights, keeping their smooth surfaces visibly different from the cloth.

4. Composition
Compress the far canopy panels along the image’s upper edge and open the near panels along its lower edge. Keep the hub unobstructed, show each rib meeting its own rim tip, and leave clear background around the lower-right handle so the radial construction remains easy to trace.

PRIORITY
Preserve the requested identity, count, action, composition and output settings. Apply the style rules within those constraints; a style reference must not replace the subject or layout. Within the style: Prioritize the continuous relationship between the hub, ribs, panel curves, and rim tips.

AVOID
Avoid disconnected ribs, flat triangular panels, and grain that obscures the structure.

OUTPUT
Create one portrait 4:5 illustration without lettering, labels, logos, or watermarks.

SELF-CHECK
Check that all eight ribs reach distinct rim tips and the near panels appear broader than the far panels.
