Would like to step in and drop some advice. If you want to learn how to draw anime style you need to realize that each series/franchise has a different canon for constructing their characters faces. You will typically have 3-4 variants all build from 1 foundation for smaller productions to accommodate male and female characters of various types. from there it's just different hairstyles, eyes, color schemes and minor details. For example, every single character from Naruto is constructed the same way, with the same canon. Which will be different from another popular series like Bleach or Soul eater.

I'm saying this because I want to highlight the fact that mindlessly drawing characters may be fun but you will not retain anything useful from that practice. What you should be doing is creating a template or a model from which you will use as direct reference. It's important that this model is made in 2D and not 3D because anime style, like cartoons, will deform the features in certain ways to aid in expressiveness. If you tried to model a 3D face based on a character, you'd quickly realize that it will be impossible to achieve the range of expressiveness that 2D allows. That being said, making a 3D model is often practiced in various productions as a means to get a general sense of proportions from various angles after which an artist will then draw freehand.

Beginner artists have this mentality that everything must come directly from the mind. That is far from the truth. You should be using, collecting and especially 'creating' specific 2D references, templates and models for your particular needs.
