Hoooohhh my God-Emperor.
You know, I always liked the design of the eldar, and the harlequins in particular, but I had to agree; they've never really had much in the ways of radiance. But THIS, I feel, does perfect justice to them. The idea of the harlequins being fanservicey almost seems a bit off, and yet all at once, it actually fits. I mean, they're supposed to be extremely talented dancers. It'd stand to reason they'd be a bit on the "titillating" side of things.
On the artistic side of things, this has a delicious mess of gorgeously vibrant colors that fit to the character perfectly, the anatomy is fantastic, the character herself is just mind-blowingly HOT, and the shading and pose is terrific. All said, this is a really damn good piece.
Now stand still, I have to bring down my Nemesis daemon hammer upon you for tempting me. HERESY. XD
