Girl Sketching

In this pic I just cover this girl from the Internet (it may have some mistakes as I haven't learned about human anatomy yet). However, the thing I want to emphasize here is her hair. Hair is the hardest thing to draw, even for me and some others. Just a sketch though, so I hope you guys enjoy it, and you can leave a comment here for me so that I can improve it. Thank you! Have a nice day! :v
