Need help making a glow effect

I’ve been trying to make Kazuma’s (from Scryed) eyes glow in the pic attached, but I’ve had no luck making it look effective.

Basically I’ve tried adding an outer glow to the eyes and increase the intensity with each frame in the animation, but it just isn’t looking right.

Can anyone help me out here?


What programs do you use? Why doesn’t it look right in your attempts?
