This is actually one of my favorites from you. Pure darkness, chaos, evil aura and a bit of fear. Its pretty hard to give someone the element of fear with just a still picture, since fear is based on motion and mostly sounds.
This reminds me of RD for some reason. Perhaps it's the hair, or perhaps it's the creature itself, which is mighty similar to what I imagine the spirit of Dash's rage would look like if she were defending a loved one.
