Can see that he's bald in the illustration on the reference sheet.
Unless otherwise specified, he wears a helmet, but since the helmet's color isn't consistent, it's best to include “golden helmet” in the prompt.
If you include “bald” in the prompt, he will almost certainly lose his helmet and be bald.
Include these prompts at a minimum :
dwarf, muscular, red hair, facial hair, beard,
clothe:
sandals, axe, shield
Please choose the one you like:
golden helmet or bald
