So last night after weeks of procrastinating and being indecisive, I decided to try doing an anatomy study, and because I was in a hurry I did it based on this piece of fan art I saw on twitter.

I did this in like minutes and was very tired as I did it, but I didn't really know what the heck I was doing and I struggled with constructing her body properly. I am going to attempt to study her again but I need to know what I should do next to improve at doing this. Any advice you guys could give me?
