That image was done by pure prompt - no reference images. Here is the prompt:
The image depicts a high-stakes, violent clash between two humanoid adventurers and a massive, supernatural giant in a cavernous, volcanic setting. Aspect ratio is 3:2. Dutch angle.
The Fire Giant
Scale & Physique: Dominating the right-hand frame is a colossal Fire Giant. He is muscular and broad, dwarfing the human figures. He is kneeling down and leaning forward. His skin is charred and grey.
Headgear: He wears headdress made of a bleached white animal skull with horns. A long mantle of white fur and chitin is attached to the headdress and draping over his shoulders.
Expression: His face is contorted in a roar of rage. His eyes glow a menacing red.
Equipment: He holds a massive scimitar in one and wears heavy, dark metal gauntlets. He has just swung his scimitar and the blade has cut into the ground. His other hand is reaching for the elf (below).
The Heroes
The Spellcaster (Center-Left): An elven figure is jumping in mid-air. She is very close to the giants face - just a few feet away. She is dressed in wintery, fur-lined leathers and heavy boots. She has her back mostly to the viewer, extending an arm toward the giant. A burst of brilliant, blinding blue-white magical energy erupts from her hand. She has a staff in the other hand.
The Warrior (Bottom-Right): In the lower right corner, next to the giants sword, a male human fighter stands on a rocky outcrop. He wears scale armor with a tattered red sash. He is wielding a straight, single-edged sword. He is looking upward, poised to strike at the giant.
The Setting & Background
Architecture: The battle takes place in a monumental hall with high, vaulted ceilings and massive cylindrical columns, suggesting a temple or a fortress built by giants.
Atmosphere: The air is thick with smoke and ash. The ground is uneven stone, with cracks glowing with volcanic heat.
The Hell Hounds: In the background, between the columns, you can see two Hell Hounds—demonic, fire-breathing dogs. They are chained up but straining toward the fray. Their bodies are wreathed in flames, and their eyes glow yellow-orange.
Painting Style & Artistic Technique
1. High-Fantasy Realism
The style is quintessentially "modern fantasy art, grounding the fantasy elements in realistic lighting and anatomy. The textures of the fur, metal, and stone are rendered with high fidelity.
2. Dynamic Composition
It uses a strong diagonal composition.
3. Color Temperature Contrast
The image relies heavily on the juxtaposition of warm vs. cool colors:
Warm: The dominant palette is an oppressive, hellish orange, red, and yellow, representing the heat of the fire giant and the environment.
Cool: The magical spell introduces a sharp, piercing electric blue. This not only draws the eye immediately to the point of impact but visually represents the "heroic" element cutting through the "villainous" environment.
4. Painterly Texture
While digital, the piece mimics traditional oil painting techniques. You can see "brushstrokes" in the smoke and the blurring of the background elements, which adds motion and keeps the focus sharp on the combatants.
