J. Scott Campbell head studies. A bunch of sketches for the game I'm working on. 

 Dragons. I spent a lot of time flipping through the art books for Skyrim and How to Train Your Dragon for these.

 Elemental Exploder. These guys are other worldly magical spirits so I was able to be all over the place in terms of design.

 Elite archers.

Slashers. The swords are magical and take on the powers of the different elements.
