Heart shape rendered with particle effects and gradient lighting

Digital composition featuring a geometrically symmetrical heart form positioned centrally within frame. Internal surface contains dispersed luminous particles with varying opacity, creating textured depth. Color palette transitions from magenta and pink gradients in the heart structure to warm orange and amber tones at lower third, shifting to cool blue and purple hues in upper background. Bokeh effect with circular aperture-blur elements distributed throughout, ranging from 15-40 pixel diameter. Technical execution employs layered transparency with additive blending, producing glowing halo phenomena around particle clusters. Lighting source appears diffused, creating soft shadow gradation across heart perimeter.
