It seems that as you kept creating, you gained confidence and a design you wanted to challenge yourself with came to mind! While it's good to follow the lecture exactly, I believe trying to create something new like that is also an excellent way to learn. Even if you didn't achieve the desired result, the experiences gained from experimenting with various things and using different functions will be accumulating. And this will undoubtedly serve as a solid foundation for even better skills. I think it would be great for you to keep trying and challenging yourself in the future! I'll continue to support your enjoyable Blender studies! :)
