An interesting addition to the Dwarves! I love me a unique Dwarf, and Direfury's model as the base helps get there, even if it's originally a MK remake. I appreciate making him heft a giant hammer with both hands; we don't have a lot of 2H-Dwarves that I'm aware of.
You know about the issues with animations, so I'll leave that alone. They aren't horrible but they could be improved, certainly. You might consider working a bit more on his posture/form; the shoulders especially look very very wide & blocky, moreso than you see on a Dwarf usually. I also kinda think you split the difference in a weird way here with Bronzebeard & Wildhammer; would be nice to trade out the helmet/armor for something more WH-y. Decay anims seem really important. The hammer could be a bit less 'square'-blocky. And I'm very confused about what Walk & Death Alternate are for; there's no Morph or even Stand Alternate, so what is the idea for their usage?
That all being said, thanks for the upload. (oh & don't forget an in-game screenshot, that's necessary for an upload)
