Discord Horror

This is my submission for the new competition in the #MLPFriendshipIsMagic group, which specifies two villans in the picture. I've managed to squeak this in on time despite Photoshop going down.
This is my first effort with SAI a friend sent me to help out on this so thanks!
For those who have not seen "Rocky Horror Picture Show",
Discord and Chrysalis are Cosplaying as the sibling "minions" who are really running things behind the mad doctor's back; Riff Raff (A Handy man) and Magenta (The Maid).
The MLP Color keys by KT were an invaluable help; [link]
