Like Addi's advice, you will need to decide on what you want to showcase in your portfolio. You need to figure out where your interests are. Maybe you want to go for character design and animation or motion graphic designs, animations of logos and simple elements.
When you decide on this, you will need to think about the purpose of your portfolio. Are you going to use it for applying to a specific job during your interview process, or do you want to persuade a freelance carrier?
When you decide what you want, start exploring websites like Behance, Dribble and Muzly - inspire form creators, artists and other 2d animators, examine their work. The next steps will be to start small - create one project at a time, think of how you will present it, create a case study, think of the details.
- For character design, you'll want to incorporate artwork that shows you can create a variety of characters with different shapes, heights, ages, abilities, clothing, accessories. Come up with an original character and show who that character is through art. If you're feeling stumped on ideas, Character Design References on Facebook has a monthly themed challenge!
- For storyboarding, you'll want to create simple, straightforward artwork that shows you can tell a story using angles, framing, lighting, and perspective. These do not need to be fancy or sophisticated, because in the real animation world, these get scrapped or re-worked constantly! What matters is you can communicate the mood or action in the story, and can draw these quickly.
- For environment design, include artwork of scenery! It can be real, like your room or inside your favorite cafe, or it can be imaginary like a magical forest.
