Thanks for reading Larissa.
Yes, for motion graphics, Video Copilot is a good place to start.
For 3D, checkout Blender Nation. It’s a nice community with plenty of resources for learning Blender—a free 3d program used by the makers of Monument Valley. Also note that with a bunch of 3d software out there, it can be overwhelming and difficult to know which program to choose. But once you get a good understanding of the fundamental concepts, you’ll be able to use any 3d software. Hope this helps Larissa.
