Really nice! Do you plan to add animations?
Well...since you asked...
You could have some kind of "charging up" animation, where some sort of energy pulses through one of the rings, or the lights on the ring light up / fade away.
Or you could have the eye "blink".
Or you could make both rings orient themselves as "O" and then spin quickly.
It looks like you're rendering these in 3D and then pixelating them, which I think is great. Which is why I am suggesting such extravagant animations. :D
