Build your animation portfolio

If you are interested in becoming an animator, either in 2D, 3D or stop-motion, you will want a portfolio of your own work. This can include a showreel as well as illustrations and drawings to show off your artistic talent. Start this as early as you can and update it as you improve and get more experience.
