This dude is just your standard rank and file cannon- fodder guardsman, no doubt soon to become a Tyranid toothpick or have his head burst by the fiendish machinations of the chaos gods. Poor bloke. I always liked the guard- I mean Space Marines are all very well and good but they only account for about a tenth of one percent of the Imperium's fighting strength. In terms of sure volume, it's the Guard who win every time. Plus they get tons of cool tanks and shit.
I freakin' love Eldar. That's all there is to say about this dude. Somewhere, lost within the pages of my books or on a dusty hard drive somewhere there's a pretty cool picture of a Harlequin Deathjester. I'll see if I can find it.
