1. The image is not very complex, but the code is too long. What should I do to make the code shorter and more clear? 2. Locating the right spots of the symmetrical image is not very easy, which costs me a lot of time. Is there any way to produce a symmetrical image easier? 3. I wanted to make an image like this ⬇️ at first, but I didn't figure out how to produce the image inside a circle.
