"Design a scene where the shadows of the Ghaf tree form the letters 'G H A F.' The text should appear as if it’s being cast by the tree, featuring intricate patterns within the shadow. Use a gradient background that mimics a desert sunset, with warm hues transitioning from deep oranges to soft purples, enhancing the silhouette effect of the tree and text. The overall composition should evoke a sense of tranquility and cultural richness."
