I agree, the shadow does more for the picture than the glow. :)
I disagree. The background has a distant and radiating effect, seemingly brighter than the subject. I would use the chartreuse color for the outer glow.
I prefer the no shadow subtle glow-she pops more in that one.
Outer glow, I don't like the shadow version much.
OK - between here and Facebook it's a tie, so someone's gotta step up and break it. Thanks!
