This coloring page captures a scene of three people on the run with their ill-gotten gains. The two on the sides have their heads turned away from the camera as if they're trying to stay hidden. Meanwhile, the one in the middle stares directly at the reader with an expression of either determination or dread. The bags suggest they have something to hide, and there is an undeniable tension to the moment.
In order to capture the mood of this picture, I would suggest using muted, shadowy colors. The background could be a deep blue, accented with touches of brown. The characters' faces and closest figures would be a darker hue, while the bags and other details would be a lighter shade of blue. A few splashes of crimson would complete the picture, adding an extra layer of mystery and excitement.
