The setting is a wild, rocky shore, with jagged cliffs rising in the background and turbulent water swirling around the combatants' feet. Delacroix uses loose, expressive brushstrokes, especially in the foaming water and the dragon's scaly form, creating a sense of movement and chaos. The palette is dominated by deep greens, browns, and blacks, with flashes of white and gold that draw attention to the central figures and the woman on the left.

Small details, such as the glint of metal on the knight's armor and the dragon's open jaws, are rendered with quick, energetic touches of paint. Paint is applied thickly in some areas, especially on the horse and the armored figure, while the background cliffs dissolve into soft, atmospheric washes. The horse’s mane and tail are painted with swift, white strokes that contrast sharply against the darker water and rocks.

The background cliffs on the right side are rendered in deep, shadowy greens and browns, with indistinct, blurred edges. A diffuse, silvery light falls across the horse’s back and the surface of the water, highlighting splashes and foam. The upper left and lower right corners of the painting are especially dark, framing the central action with deep shadows.

The outlines of rocks and waves are loosely defined, with visible brushstrokes and areas of exposed canvas at the painting’s edges. A partially draped female figure stands on a rocky ledge at the upper left, her raised arm holding a dark object that contrasts with the surrounding misty light. The dragon’s long, twisting tail extends across the lower right corner, its form partially submerged and fading into the dark water.

The horse’s front hooves are raised above the swirling water, with splashes of white paint suggesting the force of its movement. Diffuse light falls most strongly on the woman’s pale skin and yellow drapery, making her stand out against the shadowy rocks behind her. Loose, energetic lines define the dragon’s spiky crest and the armored figure’s lance, while the edges of the painting show areas where the paint thins, revealing the texture of the canvas beneath. Created in 1847, Saint George fighting the dragon is the work of Eugène Delacroix.
