It depends on what building blocks work for you when drawing figures. If this is how you want your primitives to look then draw your own primitives in this style without tracing and compare it to these you've just drawn to see if the proportions and shapes are consistent.

Hi, I'm still new at this but I think I might be able to help. One of the first things that I'd ask of you is to not try to draw exactly like in the videos, and specially to not fixate on If it looks the same or not. With that in mind, its important to approach anything that your trying to learn with simplification. What's the first thing I notice or think about when it comes to references? I ask myself "What am I seeing?" What are the shapes? What tilts am I seeing? If you look closely, your first upper shape is tilted slightly to the left when the reference is tilted slightly to the right, this can change the perspective quite a bit. Also, your use of line is good, I'd suggest for you to exaggerate it a little bit more so you give more life to your sketches (even a bean) and in a way, nurture your creativity. I've attached some quick sketches of the same thing but in different ways, I also got carried away and drew anything that came to mind with the same pose (good exercise to maximize your practice), the bottom right corner shows how you drew it on the right and how I drew it on the left. Again, don't try to copy everything, understand what's being said and try it in your own way how you understand. I hope I could be of some help.
