This book presents what, in my experience, is the foundation and foundation of illustration. As far as I know, no one has attempted to systematize and set out these foundations before me. Therefore, I decided to collect all the much-needed knowledge, drawing it from my own experience in the field of creating illustrations. I will try to clearly outline the basic principles that relate more to drawing in general than to drawing specific figures or other objects. I guess my readers are already pretty good at drawing and have some training in the field. Therefore, this book cannot serve as a guide for the early experiments of a beginner and will not be useful to those for whom drawing is only a hobby. It is intended for those readers who are going to become artists and are ready to make every effort and all the diligence that this profession requires. Success in art is not easy; it's not enough to just scratch a pencil in your spare time. No gift or talent, even huge, eliminates the need to know the basics, practice hard and work hard. I'm not suggesting that anyone can paint or paint. I say this: anyone who can draw or paint can improve their skills if they acquire additional knowledge.
