Design a poster that showcases a futuristic artist's studio, with AI-generated art pieces and futuristic tools scattered throughout. The International AI Art Competition title is written in a bold, handwritten font across the top of the poster, with the tagline "Where Human Creativity Meets AI Innovation" written in a smaller font below. The background is a warm, gradient beige, evoking a sense of creativity and experimentation. Apply a Vignette effect to enhance the mood and atmosphere. Incorporate a subtle compositing effect to blend the different elements together seamlessly.
