Hello! Here goes: Anatomy - The rear delt goes *over* the infraspinatus, making the top portion not visible. If you still want an indication of the insertion of the infraspinatus I suggest making the lines less dark/visible. The bottom of the trapezius should be on top of the latissimus. Finally, the triangle of the trapezius isn't that big. Don't be discouraged, I like your drawings! Other - I suggest working on structure a bit more, ignore anatomy for a few seconds and just focus on the shape of the shoulder (it's 2D silhouette) and making it feel interesting. Keep at it! Nice work.

Hi! What are the possible "roles" of sculpting in an artist's career? To sell the final product? Make maquettes for projects? Thank you and have a nice day.

Hi Daniel! If I may, I suggest using lighter guidelines, make more usage of the dark ones and add a small indication of wedging and sharp bone area (through sharp dark corners) like on the elbows, knees and sometimes wrists. The 3rd gesture drawing from the 1 min set, counting from the top left, is a great example of what I suggest you focus on replicating.
