Vibrant Hot Air Balloon Shaped Star

Create an image featuring a vibrant hot air balloon shaped like a star, composed of a mix of colorful spheres in shades of yellow, blue, and purple. The balloon should be lifted above a whimsical landscape with gentle rolling hills, a grassy field dotted with multicolored flowers, and a clear blue sky filled with fluffy white clouds. Remove any brand elements and include whimsical shapes like stars and butterflies floating around the balloon for an enchanting touch.
