Thanks to 3D Studio Max Autodesk software. I followed courses about modelling 3D. Mainly the tools that allows you to start from a simple box and end with a complex and realistic shape.
Then I learned everything about creating materials to apply on surfaces. How textures and UV works in order to make good looking models.
The last step of my schooling was about animation. I learned to put rig on characters and how to add animations to it as well as handle animation timeline.
