The coloring page presents a large, burly man with imposing features. His shaggy black hair and bushy beard frame a strong face, with eyes that seem to convey a message of strength and power. He appears to be dressed casually beneath a long black coat, one hand tucked beneath the fabric and the other by his side. His hands and arms are muscled and look like he could crush anything that stands in his way. He looks like someone not to be messed with.
When it comes to coloring this page, I think using a bold canvas of muted blues and grays will bring the character to life. A splash of bright red on the coat would be eye-catching and give the man a sense of danger, while deeper blues and grays on the hair and face would focus the attention on the strong features. Other colors to consider including a cool green on his eyes, and a deep yellow to add warmth to the page.
