I want to draw portraits realistically but everytime I try to copy photos it doesn't looks like the reference and I can only draw features decently when I'm drawing it separately. There's a lot of things I need to work on but what is it that I must focus on based on my skill level?

Yanna. She can read multiple books at once just by touching them but the amount of knowledge was overwhelming making her scream everytime she use her power. Because of that, people in the library was always disturbed by her sudden shout hence she decided to make a sound proof mask to be able to read and scream as much as she wants without bothering other people. She also use skates so that she can catch up to wherever she is needed. Her goal is to spread every knowledge that everyone needs to know
