Adobe After Effects

Recently I have been learning how to use Adobe After Effects. To help me advance my skills on this programme I used a tutorial to navigate me way around the software.
To create this Glass Shell I used a tutorial (http://www.videocopilot.net/tutorials/glass_orbs/), this allowed me to understand how to create an animated sequence.

My main issue was getting the orb to begin to move, all the other steps were easy to follow and understand. I feel I have a better understanding of the programme and would be able to advance by following other tutorials.

I'm hoping to use this in my main task as my production company logo, however the image inside of the orb may be different. This is because I think a galaxy or plant will look more effective from inside.
