The man in the picture looks worn and desperate, as if he has seen more than his share of trouble. He is standing in front of a crowd of people, with a broom and a bucket held in each of his hands. His face is long and thin, and his pale hair is disheveled and unkempt. His clothes are torn and ragged, and his mustache is thin and weak.
To bring out the emotion of the scene, use soft warm colors that are muted with gray. Paint the figure with an olive-based brown and then use light browns, blues and grays for the shadows on his face and clothes. For the crowd, a cool gray or blue could be used to convey the feeling of hopelessness and despair. A bright yellow for the bucket and broom could provide a bit of contrast. Finally, some pops of brighter yellows and oranges in the background could brighten the image and bring it to life.
