King Fergus is an imposing figure with a broad chest and muscular arms. His dark beard and mustache are a distinguished feature of his regal stature. He wears a traditional kilt and a shimmering gold crown on his head. He holds a sturdy sword at his side, symbolizing his heroic strength and power. In the backdrop of his kingdom, a mighty castle stands proudly, its tall turrets reaching towards the sky.
For coloring this image, you could use bright and vibrant colors to depict the grandeur of his kingdom. Use dark blues and greens to represent the walls and towers of the castle, and give Fergus a bold and confident look with oranges and reds for his kilt and a gold shade for his crown. The sword can be painted in sharp silver to give an authoritative glint. For an added layer of detail, use yellows and whites to create a sunlit sky above and behind the king.
