A surreal dark animated-cartoon illustration: a large expressive human brain with a mischievous face is eating a stylized anatomical heart, using a tiny fork and knife. The heart drips bright red blood that becomes a winding river flowing through a shadowy dreamlike landscape. Dramatic moonlight, vivid red reflections in the river, cinematic composition, macabre but non-photorealistic, no text.

A surreal dark animated-cartoon illustration: a large expressive human brain with an open mouth is directly biting into a classic red heart symbol, no fork, no knife, no anatomical organs. The heart symbol drips bright red blood, and the blood flows downward into a winding river through a shadowy dreamlike landscape. Dramatic moonlight, vivid red reflections in the river, cinematic composition, macabre but non-photorealistic, no text.

A surreal dark animated-cartoon illustration: a gigantic classic red heart symbol dominates the scene and is clearly much larger than a smaller expressive human brain. The small brain is directly biting into the lower edge of the enormous heart symbol with an open mouth. No fork, no knife, no anatomical organs. Blood drips from the giant heart and becomes a winding river flowing through a shadowy dreamlike landscape. Dramatic moonlight, vivid red reflections in the river, cinematic composition, macabre but non-photorealistic, no text.

Create a refined illustration based on the uploaded hand-drawn concept: on a clean white paper-like background, a small expressive brain at upper left directly bites the edge of a much larger classic heart symbol at upper center-right. A few drops of red liquid fall from the bitten heart and form a flowing winding river or stream through a sparse grassy field below. Add a simple jagged heartbeat line in the distant background. Preserve the symbolic surreal composition and hand-inked sketch feeling, but render it polished and detailed. Exclude the fairy, angel, wings, halo, healing beams, stars, and all flying figures. No text.

Refine the prior sketch-style surreal illustration: a small expressive brain is directly biting the edge of a much larger classic red heart symbol. Give the brain one clearly visible expressive eye and one bold arched eyebrow, with a determined or angry expression. A few drops of red liquid fall from the bitten heart and become a flowing river through a sparse grassy field. Add a subtle jagged heartbeat line in the distant background. White paper-like background, polished hand-inked illustration feel. Exclude fairies, angels, wings, halos, healing beams, stars, and flying figures. No text.

A polished cartoon illustration based on the prior composition: a small cartoon brain directly bites the edge of a much larger classic red heart symbol. The brain has a sinister evil look, with one narrowed eye, a sharply angled eyebrow, and a mischievous threatening grin. The giant heart is not crying and has no face, eyes, mouth, or any expression, but is shown as emotionally depressed through its drooping, slightly slumped shape, muted dark-red shading, and heavy somber posture. A few red drops fall from the bitten edge and form a winding river through a sparse grassy field below. Include a subtle jagged heartbeat line in the distant background. White paper-like background, clean hand-inked cartoon style, dramatic but non-graphic. No text. Exclude fairies, angels, wings, halos, healing beams, stars, and flying figures.
