This coloring page portrays a man playing a string instrument, which is being held horizontally across his lap. He is plucking the strings with his right hand and holding a small object in his left, while wearing a hat and a robe. For coloring, start by giving the man some definition around his face, eyes and mouth with a darker shade of color. Try to keep the colors simple. You could have the hat be in a darker shade while his robe is a lighter shade. For the string instrument, a blend of browns and grays would make it look more natural. Include some highlights on the strings and make sure to add some shading and shadows on corners and around the object he is holding in his left hand. This will give the final piece an added level of realism.
