Very nice, striking color scheme. But... is it just me or do those swords look like giant foam/marshmallow blades? :P A glowing red to match the horns might go over better, I dunno.
I'd love to see a close up shot of this, to look at the facial shading and muculature.
as it is, i love it. the swords, eh, not my style, but the figure itsself and the texture work you did on it is great. plus, i've never seen it before, and i think it would make a great basis for a conversion for my slannesh army, thanks for bringing it to my attention!
