Create realistic, natural shadows for all objects in this interior scene while preserving the exact composition, materials, colors, and layout.
Analyze the existing lighting direction and intensity in the image and match all added shadows accordingly.

Add soft, diffused contact shadows beneath the sofa, coffee table, floor lamp, vases, and all decorative objects.
Ensure shadows are subtle, slightly blurred, and consistent with an overcast daylight environment.

The floor lamp should cast a very soft ambient shadow on the wall and floor, not harsh or directional.
The coffee table and objects on it should have grounded contact shadows directly beneath them, with slight falloff.

If any added object appears slightly misaligned in perspective, subtly correct its perspective so it matches the scene’s camera angle and horizon line.
Do not move, resize, or redesign objects. Only apply minimal perspective correction if necessary for realism.

Maintain photorealism: no added objects, no changes to materials, shapes, styling, or composition.
Do not alter colors, textures, or layout. Only enhance lighting realism and correct minor perspective inconsistencies.

Style: high-end interior photography, soft natural light, balanced exposure, magazine-quality realism.

no hard shadows, no dramatic lighting, no extra objects, no repositioning, no resizing, no redesign, no color shifts, no texture changes, no added light sources, no surreal effects, no over-contrast, no glow effects
