Hey Rogerio, welcome! I would definitely recommend tackling these two courses next, as they go much more in-depth. Your experience in other programs will be more than enough of a prerequisite if you’ve gotten the basics of Blender down (selection, switching windows, navigation, etc…).

I’m looking forward to seeing what you make with them!
