About this 3D model

This is like this Tinkercad https://www.tinkercad.com/things/6qT3fqqZsLe Dear teacher, this model is from China, I am crazy but I am real. This is composed of a dragon composed of a fingertip gyro, dragon modeling is very difficult, I spent 20 days to complete this model. From the beginning of the idea to the end, I am proud of myself. Finally, I use the logo of the Chinese clouds as embellishment, this model after a lot of details are not modified, please a lot of criticism of the teacher, thanks for watching
