Reflection on a Clear Globe

Question

Here is my problem.

I have a clear Globe that is a Christmas ornament. It has a little abscrat nativity scene inside. All is good, my issue comes in when I attempt to add a reflection to the outside of the orb. It looks very fake, How would I go about adding a transparent reflection that helps the globe take shape to indicate that it is truly a globe?

I am using Photoshop CS 5.1

Answer 1

A screenshot would really help.

But for first advice, search for tutorials like this one. Or search for images that looks like you want it. For me words like "globe", "sphere", "glass ball" or "orb" where good.
