It was very long because of my pedantry. The result was a little different than what I expected.
There are still several questions on sculpting, but I hope I can find the answers to them after completing the sculpting course or you can help with advice. (Grid density - how to adequately choose a grid density?.Ugly polygons on some faces - How to get rid of "polygonization" (analog - pixelization)?. Errors in dynamic topology with a sharp change in grid density).
Many thanks to the coaches for the course!
