ctnguyen- i dont know exactly what you mean my young artist but im 17 yrs old. Most of my mates have the same problem, they can copy things easy, they just can’t take that information later on and use it. I think it may be something to do with relying on the pictures too much, maybe from this point on you dont use references and struggle for a little bit until bits of information imprint in your brain:) Secondly, do you use any structure before you add features? For example, do you sketch out the base of the head, before you add the nose and eyes? If not that may be a big problem. Finally, dont try and consume yourself with a whole body to begin with, start sketching eyes without reference, then eyes, then ears etc.
Hope this has helped you:)
Fantastic artwork by the way
