I coloured this last week but I didn't want to post it without the original artist's permission (a commonly overlooked bit of artistic common courtesy, here on the interwebs) and I just got permission this evening.

The original line art was done by THIS GUY. He's really talented and you should check out his blog for more of his stuff. You can see the original HERE but try to give the rest a look or you'll be missing out on some kick-ass stuff.
