This aging soldier is deep in thought, surrounded by books, a quill, and an inkwell. His dark hair is graying and his military uniform is decorated with medals and patches. All around him is a sense of authority emanating from his confident posture and serious expression. To bring this portrait to life, you can use earthy shades such as browns, greys and navy blue to indicate the age and rank of the man, while adding a pop of color with a vivid red to capture the courage and patriotism of a true war hero. Finish the image with white or light gray tones to truly bring out the details of the portrait.
