I watched the video several times. And here is my result. There are several points that I do not understand. First. As an engineer, I do not understand how to correctly take measurements from an object, it seems to me that the width of the pear does not match very much. The second point, I do not quite correctly how to shade the pear, but we will go through this at the end of the course and the third point. My big minus is that I cannot draw a normal difference between shadows. they do not correspond to the previously drawn values, which are at the top of the drawing

Hello everyone! I'm will be happy to show my first try.
