Here's a real secret. Bring outwhatever talents you have using whatever tools you feel will do that for you. Although it helps to know the mainstream apps, when it comes down to the crunch, it's what's coming from your brain and how your able to portray it is all that really matters. If it looks great and sells your imagination, who cares where and how and why? Remember this too. If your driving a porsche, the cool car takes away from your own thunder and they expect you to know how to drive it to performance and win. If your driving a honda civic, they'll thumb noses at you until you freak them out with your driving and by winning the race!
