Damn there Chew think they ought to be hiring you the next time they want to get some concept art rolling for L4D of better yet the Oddworld games too, lol.
Wow can't express in words how stellar and amazing this guy looks, the whole way you perfectly pose out his stalking and his charging abilities really makes you think he's about to jump right out of the screen!
Kudos though on the the way you thought to color him up, find it hard to keep an eye out for the guy cause he's so damn dark clothed but even then you don't get to appreciate the design work or his look enough like you would on a Tank or otherwise.
Still though love the additional level of insanity you add with your own lines with the gnarled up look of his hands to even the drips of blood he leaves behind him, now that's freaky. And just as much as in the game like the Big Daddy is within Bioshock well done on keeping the face hidden, never giving too much insight but all the mystery you love about a dark and misty character like this.
Hats off Chew and by the way strolled by your Pokemon pieces you've done on your other account, hell lass wish had even just half the talent as you. *applauses*
