Meet the Determined Dwarf Hero

A middle-aged dwarf, strong, with a harsh face and a determined look. He wears somewhat dented and blackened plate armor from the fire. His right arm is raised, showing a metal runic knuckle duster. His beard is short and trimmed, with some gray, and his hair is similar to the second image you requested: loose, messy, of medium length. He has a diffuse scar on his left eye (like a stain), and his eyes are marked by nights of guard in battle. At his back hangs a blacksmith's mace and stained bandages. His sacred symbol is engraved on the back of his knuckle duster. Artistic style: semi-realistic, dark medieval, dirty but heroic.
