heres my try from your "after reflections advice"
what i did was played around with the bevel and emboss blending options. what i did was made a layer of all white, over the entire "earth" eye and then i messed with the settings under bevel and emboss.
then i added a little circle for some better lighting effects, then bevel and embossed again.
Also did what i told you originally.
Only spent like 2 minutes doing this, but was just to help you out and to lead you in the right direction.
let me know if you want the .psd
