Dino Island

A brachiosaurus silhouette stands tall against a dramatic twilight sky, framed by dark tree canopies on either side. The color palette transitions from deep purple and lavender at the top through soft yellow and peach near the horizon, with distant mountain silhouettes and wispy clouds adding depth. A large full moon glows in the upper right. The dinosaur and foreground grasses are rendered in solid black silhouette, creating strong contrast against the luminous sky. The mood is serene and prehistoric-fantastical, with a moderately detailed background and smooth blended gradients.
