Problem is....it looks like the "mirror" effect is part of the dock, and not the icon. If you enlarge the icon (to add the mirror effect on the bottom) then it will probably not line up.
Check, see if its part of the dock.
PS- Im assuming this because I can still see reddish mirror under your green icon on the dock.
i did the original one had a mirror apart of the icon and its no longer there heres a pic of it with the old icon(dont pay attention to the sms app i didnt change my bitesms icon in the original)
Attach the old red icon if you will so I can get an idea of the dimensions of the mirror effect (height basically) and I will see if I can edit it for you.
