Although it looks cool, I don't feel this technique gives a realistic look. The eyes in the helmet are recessed. Therefore, a glow eminating from them would actually cast the raised plates around them in shadow, not reflect light onto them. Think about it this way: turn on a flashlight. Is the outside of the flashlight lit up by the bulb? It's a more extreme example, but it's the same principle.
The rest is absolutely amazing, though.
