Uwaa this is so cute! And man, I swear I took at least 3 hours trying to grasp the concept that is Fern's hair
Actually, I don't recommend jumping into anatomy right away if you're a beginner. Learning anatomy is really hard and boring if you don't know how to translate 3d forms into 2d. In other words, you should learn how to think and draw objects in 3d first. Anatomy, proportions and stuff like that is the second step, so don't worry about it now. I actually barely know crap about anatomy myself!
Think of 3d objects as small building blocks used to make your drawing.
I used your cute drawing to show how you can use 3d objects such as cylinders to construct a drawing. I threw in information on how to draw a cylinder as well! Sorry if all the stuff I added is an eyesore.
Of course, I'm no pro mofo artist, so I recommend reading Vilppu's drawing book if you want to learn more stuff like this. It's great for beginners and it greatly helped me when I was a beginner myself! (Even though I still am one)

Anyways, you should always keep drawing and draw what you like as well! Drawing should be enjoyable after all
