Today I decided to experiment a little with adobe after effects 3d settings. So I built a simple room, added some lighting and a camera, and proceeded to mess around a little. Making the room was difficult, but I got the hang of it by the end.
I then imported one of the drawings I'd done and moved it back in the scene, making sure the foot touches the floor or the 3d scene, and that the lighting is in a correct place for the shadows to fall.
Then I simply played around with the camera, moving it in the scene using the properties and also within the scene itself. There are a lot of possibilities for video making within these tools, and once you get the hang of them it's actually quite simple.
