Книжный футляр — вариант 1

Use the supplied image as the exact reference. Create one isolated transparent PNG of the same subject: three small navy leather books inside matching slipcase with subtle gold ornament, no lettering. Preserve its recognizable identity, material, original natural colors, realistic tactile studio-photography style, soft diffuse upper-left light and three-quarter view. Make the variant about 20% visually different through a clearly changed silhouette and several object details, exactly as described here: A squat wide navy book set with three thick volumes, broad spines and a low rectangular slipcase. Keep the original color family and change hue only slightly. Redesign any small surface ornament or trim to suit this variant instead of copying an identical pattern. Keep the entire object centered and fully visible, occupying about 75–80 percent of a square canvas with generous transparent margin. True transparent alpha outside the object and through every real hole or gap. No floor, scenery, backdrop, checkerboard, external cast shadow, detached pieces, text, logos, border, watermark, extra objects, animation or montage.
