I like the idea mate. Usually when we create motion graphics, it is to tell a story or enhance an emotion. I don't see either of this in your design. There is too much going on to get a grasp of what is happening. If you were going for some kind of windows media player screen saver for music, you nailed it. Other wise try and give your project some kind of direction instead of throwing together experiments with plug-ins and calling it quits. I do see a lot of potential with your video. One thing to note is color, visit kuler.adobe.com to get complimentary color styles and stick to them. Most the time, you want to avoid 100% black and 100% white. I hope this helps. Keep producing stuff man! It is the only way to get better.
