Didn't have one in the long arms because it wasn't asked for. Not sure what their stats are in the DnD system, so even just fluffing a wheellock musket (like I did with the two gonnes) wouldn't have been a good idea, especially considering time and size constraints.
As for them looking Dorfish, that depends on the setting. This setting has Dorfs but they aren't detailed in the part we're working on. What I wanted with Elvish materičl was post-Medieval designs built using Medieval sensibilities. The Renaissance man was way more advanced than the Medieval man, like Elves are to Humans, and I figured that would work well enough. The setting was described to me as post-apocalyptic fantasy, and I stuck with more historical influences for my work.
