Step 1: Brush on Primer
Step 2: I basecoated him with Troll Slayer Orange, The Fang, and Steel Legion Drab. I basecoated the base and the bracers with Mechanicus Standard Grey.
Step 3: I washed the troll with Carroburg Crimson. I also washed part of the base near his fiery foot with Carroburg Crimson.
Step 4: I overbrushed the flames with Troll Slayer, and the skin with Thunderhawk Blue. I put some edge highlights on the bracers with Administratum Grey.
Step 5: I overbrushed the flames with Fire Dragon Bright, and the skin with Russ Grey. I washed the rest of the base with Nuln Oil.
Finished! I drybrushed the flames with Kindleflame, and the skin with Etherium Blue. Then I lined the flagstones with Administratum Grey. He got a red eye too.
I lined the red washed stones with Fire Dragon to finish off the glow effect.
