Creating a portfolio and demo reel is crucial for 2D animators. It's your chance to showcase your best work, highlighting your unique style and technical skills. A well-crafted portfolio can open doors to exciting opportunities in the animation industry. Your portfolio should include a variety of work samples, from character designs to finished animations. It's important to regularly update it, removing older pieces as you create stronger ones. Remember to tailor your portfolio to your target audience and include brief descriptions to provide context.
