Need help drawing crystals

2 props I've drawn. They're supposed to be crystals sitting a on a shelf looking all shiny and pretty.

But as you can see the first one looks more like a bowling ball or a globe and the second one looks like a christmas tree. I've fiddeled around with these for a while now and I can't seem to figure out what makes a crystal look like a crystal.

They look pretty good, IMO. I did some for fun, looking at some examples of crystals and crystal balls on google. Not great, but I tried to include some transparent, glowing qualities.

perfect  glowing shiny and expensive. i liked it!

I think the problem with the ball was too big specular radius. Glass/crystal objects tend to have strong but small reflections of light instead of biiig spots. Evil catched that quite nicely in his edit

Thanks for the drawover Evil, the sphere does look alot better like that. It gives atleast the apearance of being a crystal globe.

I'll try to find a good referance picture that'll suit my needs for it
