Cheerful Cartoon Llama Blank Sign

Create an illustration of a cheerful cartoon llama holding a blank sign. Instead of a brain, have a light bulb drawn in a simple, stylized manner, with playful swirls around it to suggest creativity. The background should be a soft pastel gradient, blending shades of blue and pink for a warm, inviting feel. The llama should have big expressive eyes and a friendly smile, with a slightly fluffy texture to its fur.
