masterpiece, best quality, The smoldering heart of Volcano Lands. Jagged obsidian rocks, slick with cooling lava, form a natural pedestal.  Flames lick the edges of the scene, casting dancing shadows and sending plumes of smoke into the ash-filled sky. Molten, glowing heart, pulsing rhythmically.  Every beat sends ripples of fire across its surface.  The lava within is a vibrant, fiery red, almost white-hot at the core.  Tiny fissures glow like veins of molten steel, catching the light. Exaggerate the heart's shape a bit - make it a touch more angular, maybe with a point at the bottom.  Think dramatic highlights and shadows to emphasize the heat and texture.
