A cinematic and photorealistic image of an epic fantasy battle scene in a vibrant but slightly muted forest. The focus is on a valiant paladin wearing intricately designed armor, with a subtly glowing sword and shield in hand. Next to him stands a mysterious wizard draped in a hooded robe adorned with complex arcane symbols, while a softly illuminating orb crowns his staff, casting delicate shadows over his hidden face. To the other side, a skilled ranger is depicted in a detailed leather cloak, armed with a longbow poised for action. Their adversary is a grand, three-headed dragon with elaborately detailed scales in a subdued palette. The forest's lighting is sharp and natural, enhancing the crisp, vivid details of the characters and surroundings, creating a scene that's enchanting yet slightly melancholic.
