The Beast and Belle seem to be celebrating something in this image. The Beast is wearing a red shirt with a black vest, and black pants and shoes, while Belle is wearing a bright yellow dress with a white scarf around her neck. The backdrop is a beautiful room, with a wooden floor and stone walls. On one side sits a table with a white tablecloth and a red rose atop it. To add more depth and color to the image, fill in the black clothes with a deep blue and the yellow dress with a light peach. Use pastels to fill in the background, such as light blues, pinks, and peaches to capture the serenity of the environment. The Beast's fur can be darkened with a light brown, and Belle's skin can be lightly shaded with a light pink. The rose can be colored to be a deep red. Finally, add shadows and highlights in the appropriate places to give the image a more finished look.
