Wow, Elson, I really love this drawing. Very dimensional!

Hey Elson! Great job on this, I can definitely tell it's a study of Stan's. The anatomy, edges, proportion and gesture are getting there. What I would say is to focus on trying to understand the forms and how they're moving in space. Right now it feels like more of a copy of someone else's drawing rather than interpreting those shapes in 3D space. What I mean is it feels sort of flat. You did a good job placing everything, but it doesn't feel like you understand the underlying anatomy yet. For example, his left scapula and how it relates to his traps/ deltoid is correct enough for me to understand what's going on when looking at the entire drawing. When I zoom in though, it doesn't really feel like a shoulder. If you were to really try to nail down where things insert/ how the traps sit on the scapula it would do a lot for making it look more 3D and allowing you to interpret that information yourself. Hope this helps!
