Here are some clips from my animations for a project on passive, aggressive, and assertive behavior. It’s about learning to be assertive and stand up for yourself in tough situations without being too aggressive.
On another note, because I work in both 2D and 3D I really like blending the two together to produce final pieces. My friend and former professor Tina O’Hailey has a textbook about doing just that. If it’s a subject that interests you I highly recommend checking it out the book is called Hybrid Animation: Integrating 2D and 3D Assets. It’s a great resource for a 2D/3D workflow in a few different software packages.
