Heart-shaped luminous form hovering above waterfall in vibrant fantasy canyon landscape

Digital 3D render employing volumetric lighting techniques within canyon environment. Central magenta heart element positioned mid-frame, emitting radial glow against cool-toned atmospheric haze. Cascading waterfall descends left-center with procedural water simulation. Overhead canopy trees rendered with neon pink foliage. Scattered particle hearts distributed throughout composition. Lighting architecture uses rim illumination on geological formations, cool-blue ambient occlusion in shadow zones, warm magenta key light sourced from upper-left. Post-processing includes bloom effects, chromatic treatment, and depth-of-field gradient.
