Nightmare 6 Teaser

Here is the project I have been working on between commissions for this year's Bronycon. I wanted to make a big impression like I did with the Knights last year and I hope to do it with the Nightmare 6 (think the four horsemen of the Apocalypse only there are six of them...and there ponies). I hope to have these prints made by the time the convention rolls around. 

Most of them control their own army (armies that will look familiar to those that have caught up with the show)

Can the Knights of Equestria defeat this group that is hell bent on destroying everything in their path?
