I think they look savage! I like the colour scheme- sinister purple, torn flesh beige and raggedy muscle red. I could name my own GW paints! They will tear your opponents a new one. Lots of attacks and invulnerable saves, they will stick around until you are munching alien on the other side of the board on turn 2. Where are your beast masters? I just went the Hellion route for mine.
Kia Kaha, Dark Eldar players!
