@Nikita Kapustin not so difficult as seen.. And will help you in comp modeling "vision" as well 😉. I recommend 1 course with real lector (figure sculpting 10 2-hour lessons), phen videos and books of Philippe Faraut, and finally video courses on proko.com (!) Mr. Prokopenko and his partners. Clay is cheap, some spatula from AliExpress or local art shop as well, you can do it at home 😉, as me.. And molding somewhere outside or if ceramic, some ceramic ateliér usually allow you to burn it.. 🤞. Wish you good luck for your activities.

@Nikita Kapustin nice statues of classical figure is full in Louvre and Orsay in Paris.. You can make plenty of photos, just on place, one statue from different angles, etc.. no restriction.. So many of them, that you have stock for whole life, maybe two.. 😉

Please as beginner, I would like to reproduce everything what is in course at home, so it could be useful slower speed, and knowledge, what exact keys, shortcuts, menus was used. And also explanation of concepts, union, boolean operation with examples.. And to have this solid knowledge, I can build on it..
