Great art, were you perhaps inspired by the One-Eyed Owl?

I don't know why, but I really love the design and the red + purple combination. Also the metal looks amazing, and it brings out the things I mentioned. The only thing that I don't like is the small white light over the big eye in the middle which I think is a little distracting. But that's just me nitpicking, though.
One last thing, though: THE EYES. The one huge eye and the four tiny eyes are really interesting to look at, since staring at the small eyes makes him intimidating while staring at the one big eye makes it just look unsettling. Actually, the entire thing looks unsettling (which is probably what you were going for but hey).

I understand that this is a doodle, but it looks amazing even with that in mind. :D
