I gave my all with this final entry into the Riddick contest and all of this is hand drawn from references. This challenged me in every way and I hope you like the finished piece. There are still details that I want to work in if I can find the time but I wanted to share this with you all now. All of this is drawn in Photoshop and any additional references used belong to me.
EDIT: As this has come up a few times I wanted to reiterate that this is not a photo and is all drawn.
