[Skin] Pre-transformation Warwick

A skin somewhat akin to pre-void Kassadin. According to the lore, Warwick was a savage long before his official transformation into one. A skin showing what he looked like as a human I think would be pretty cool to see. Something similar to the image in the "Extras" section of his update page where he's seen in the background hanging from the ceiling while Singed stands in the foreground looking mildly perplexed.
