Create a pixel art image of a small, rusty robot with expressive LED eyes, offering a red heart-shaped balloon to a young woman. Use a limited 16-bit color palette with muted tones and subtle dithering for shading. Highlight rust textures and mechanical details with crisp, clean pixels. Apply strong outlines for readability and add slight color bleeding for a retro feel. Position the characters using the rule of thirds, with warm lighting creating soft highlights. Keep the background minimal with gentle gradients to emphasize the emotional moment. Focus on perfect color harmony and charming character design.
