Looping and Transforming Masks

Originally for this project I wanted to make a title card for Beat Brothers, but I soon found out that each letter would create a mask and even the inside of the letters were masks. So things got pretty confusing pretty soon. So I decided to create something more simple. I made a basic loop cycle that I wanted as a back ground for my first idea, but just used it as the back ground for the final concept I made. After Effects is still growing on me because Im not completely confidant in my abilities with it. Again I hope to get familiar with the program so I can use it to the best of my abilities.
