Here I have experimented with exaggerated silhouettes to quickly concept ideas for the witches true from.

Using this technique I can quickly express my ideas and experiment with silhouettes as well as detail at the same time. This is much faster than traditional pencil drawing and is far better suited for the task of speed concepting than traditional pencil drawings. 

I wanted the witch to have some kind of concealed true form she hides from her unsuspecting victims until the last possible moment when there is no hope of escape.

The witch is in a seance being enhanced and empowered to far greater levels by tapping into the currently dormant Demon God Naz,ji,kile feeding on the fallen god's energies that have permeated throughout the lands ever since Naz,ji,kiles imprisonment five thousand years ago at the hands of the Dark Heart linage.
