Sci-fi Sword (Destiny Fan Art)

I've been on a super hard Destiny kick, so I figured I may as well make some cool art and try to emulate the awesome art direction that they created. I'll be doing a weapon for each class relative to their super, and this one is for my favorite of the three, the Warlock. Also, to further my Substance skillset, I'll be making the base materials for each of these. This project will probably evolve into an environment piece, but I'd like to establish a style that will compliment my hero props before hand (And have some materials to start out with).
