Two cartoon figures holding glowing red heart particle effect

3D rendered animation featuring two mouse-like cartoon characters positioned vertically with clasped hands underneath geometric fragmented heart form constructed from thousands of small polygon shards emitting warm red-orange luminescence. Bokeh background contains teal-to-blue atmospheric haze with soft-focus particle scatter. Foreground dispersed with scale-varying heart-shaped particles in crimson tones. Technical execution demonstrates advanced particle simulation, volumetric lighting implementation, bloom post-processing, depth-of-field separation between subject and background elements.
