Dark heart with glowing red core suspended in misty atmosphere

Digital painting rendering employs layered atmospheric perspective with particulate fog effects throughout composition. Central heart form constructed from black organic tendrils with fractal branching patterns radiating outward. Interior illuminated by crimson radiant energy source with jagged lightning-like vein formations creating luminescent pathways across dark tissue. Background atmosphere rendered in muted teal and gray gradients with volumetric depth and soft bokeh. Tonal contrast ranges from deep blacks in structural elements to bright red luminescence in core cavity.
