Sketch these quickly, each shouldn't take more than 2-3 min. You'll need a lot of practice to get it perfect on your first try. Your careful work looks good to me, which means you've understood the basic concept.
anime head drawing looks easy until i try different angles
Artist's notes:
I’m trying to sketch anime heads from different angles but they always end up tilted or uneven. I think my construction and perspective need work. I’m using pencil, any feedback on what i should be doing differently?
