Digital fantasy painting of an armored knight riding a dragon

A digital fantasy painting of a knight in ornate, gold toned plate armor riding a massive red dragon. The knight sits atop the dragon's shoulders, holding a long sword pointing downward in one hand and grasping a weapon hilt on his hip with the other. He wears a closed face helmet and a flowing red cape. The dragon is a massive, quadrupedal reptile covered in thick, rough, orange and red scales, with sharp bony spikes protruding from its head, back, and limbs. It has a fierce expression with sharp teeth visible in its partially open maw. Its large, red leathery wings are partially raised. The scene is set in a dusty, hazy environment with warm golden light filtering through, highlighting architectural details of stone buildings in the background, suggesting an ancient city street covered in smoke or dust.
