This coloring page portrays a small, unkempt creature with large, pointed ears, wearing tattered clothes. His face reveals a sense of distress and he is holding his hands out in a pleading gesture. To best depict his sad expression, you could use muted colors such as browns, blues, and greys. Using darker tones around the eyes and mouth will create an even more dramatic effect. Additionally, brighter colors could be used on the clothing, such as purples and oranges, to give an otherwise drab drawing some more depth and interest. Finally, some white highlights around the edges of the figure can create a sense of volume and life.
