After a few months of work (during my free time) this is my final result of the Chris Plush Master Car Creation in Blender course that I recommend to anyone who wants to improve their knowledge of Blender (not for beginners, but I would say from mid level).
The course is very detailed, well done, long and it is almost impossible to go wrong because Chris really guides you step by step. It works with recent blender versions (2.90).
