Create an abstract illustration of a human-like figure representing the emotion of joy, melting into vibrant colors and shapes. The artistic style should be fluid and dynamic, with a focus on movement and color. Use digital painting as the medium to achieve a smooth and polished look. The background should be a gradient of warm colors, transitioning from a soft yellow to a bright orange. The figure itself should have a loosely defined form, with features that blend seamlessly into the surrounding colors. Use bright, saturated hues like yellows, oranges, and pinks to convey the warmth and energy of joy. The melting effect should be fluid and organic, with colors dripping and blending into abstract shapes. Apply a soft glow effect to enhance the vibrancy and a slight motion blur to convey the sense of movement and energy.
