I'm glad you can see the difference. The Ogre is a big brute but not comic relief, should work well as a crossover mini, but have a style of its own. In addition to the Halflings Sniper, the Halfling faction would include Operatives, Halflings in street clothes, trenchcoats, and the like who attempt to blend into the Slums and gather intel.
The plan for Elves is for them to fall into a Yakuza/Ganster role. Business suits, Katanas, Pistols and SMGs. The Yakuza Enforcer will be a big honking Sumo sized elf. The artist is working on some concepts for the Dwarf SWAT team right now, but as soon as he has those finished up, I'll see where he can go with the elves. If things take off, there will also be an Elvish Biker gang and Elves in various Slummer roles.
