[Calchet]

If you don't mind, I think I could pull off a pretty good tabletop dwarf or seven you could work from - I'm thinking something like the attached mockup sprite, though larger. (That one was mostly to see how small I could get it and still have it look dwarfish.)

(That said, it's as previously mentioned still your mod, and you're free to interpret dwarfs as you please - I might make an alternate set of graphics for my own personal use if I ever get around to it, though.)
