The two young men standing in front of the stone wall seem to be looking towards something in the distance. The one closest to us is holding a bow and an arrow in one hand, and a belt with a knife in the other. His companion likewise has a belt with a knife and a sword in his hand. The scene looks quite impressive, one of adventure and strategy.
In terms of colouring this page, I would suggest using a blend of dark and muted earth tones to reflect the feeling of the stone wall. Then for the two figures, adding more vibrant colours would lend energy to their features. A bright blue for their eyes, deep red for their clothing, and golden yellow for their weapons would create an exciting contrast. For extra detailing, add touches of grey and black to indicate shadows and highlights.
