When I used to play 40K I had a color scheme very close to what you got here except I used electric blue instead of your green scheme. But I am definitely strolling down memory lane looking at your forces.
Primarily Cygnar. But I have a small mercenary force around Ashlynn, that really consists of mercs you can field with Cygnar. I've recently started a Trollbloods force for hordes as well, but its pretty small though. And I'm thinking of getting a Retribution of Scyrah force as well. I love the game. So much better in the long run than 40k or fantasy battles.
