Here are a couple 3D animations I did for a 3D class I'm taking this semester. We were given animated models provided by our professor and had to follow specific requirements for each video. The first was just to put the pencil like model in an embarrassing situation, the second was to animate a character to music.
Just a little disclaimer, the ocean used is a pre set model in Maya, so that wasn't modeled or animated by me.
3D definitely has a learning curve, but I'm certainly liking the animation portion :)
