3D Model: Create A Highly Detailed, Realistic 3D Model Of A Dove Perched On A Stone Bridge, Suitable For High-resolution 3D Printing. The Dove Should Have Finely Sculpted Feathers With Natural Texture, Subtle Asymmetry For Realism, And A Calm, Lifelike Posture (slightly Tilted Head, Relaxed Wings). The Bridge Should Feature Aged Stone Texture With Cracks, Moss Details, And Realistic Brick/stone Patterns. Ensure All Parts Are Manifold (watertight) With No Holes Or Non-manifold Edges
