It's the beards. We just have to normalize bearded female dwarfs.
Kaldheim had my favourite female Dwarf art.
Anyways instead of leaning into Norse mythology so much, go Greek, the Kabeiroi were the Dwarf sons of Hephaestus (some say Zeus as Father instead), although they lean abit more towards Azor perhaps then regular Dwarves. I think Hephaestus was one of inspirations for Moradin, the head of the Dwarven Pantheon. Actually like was the inspiration partly for several Dwarven Gods I think.
Theros should have had Dwarves (and Angels, Werewolves, and Vampires based on mythology/theology).
