The page is depicting two powerful warrior knights. The knights are dressed in shining armor and each carry a mighty sword. Both warriors appear ready for battle, fierce and determined. It would be a fantastic scene to add some color to, suggesting the luster of their armor and the power of their weapons. Perhaps you could use dark blues and grays to suggest the shadows and the might of their presence. Meanwhile, vibrant golds, oranges, and yellows could be used to bring out the brightness of the armor and the sheen of the swords. If you add some dark greens and browns to the background to emphasize the texture of the land, it could complete the feeling of these warriors ready for a fight.
