Create a stunning and vibrant image of a beautiful princess riding on the back of a colorful dragon. The princess, with long flowing hair and an elegant dress, sits confidently on the dragon's back, her hands gently holding onto the dragon's neck. The dragon, with scales shimmering in all the colors of the rainbow, soars through the sky, its wings stretched out and claws ready to grasp any prey.
The fantasy world they inhabit is a beautiful one, with majestic mountains, lush forests, and a sparkling river winding through the landscape. The sky is a brilliant blue, with a few fluffy white clouds adding to the idyllic scene.
As the princess and the dragon fly over this magical land, a sense of adventure and wonder is evoked. The princess' face is filled with joy and excitement as she takes in the breathtaking views.
