Dark Pact Idea

After editing a past image, this is the end result, which is to help illustrate my idea for the main characters "taint." Should he become too corrupt, he will turn much more demonic and violent. This is visually evident by his right eye looking akin to a "Demon's Eye." Game concept wise, is this form, he becomes much more powerful with Darkness based abilities and becomes much less aware of oncoming attacks, but overall his physical strength is increased.
