Ok Hifsa ^^ This is a tutorial on a quick Tomoe how to. As you can see I use four basic steps when sketching/drawing. I start out with just a circle and triangle for the face. Then I add in my face proportion lines. After I follow with the ears, eyes, mouth and nose. When i'm sure they are where i want them to be I outline in pen and erase.
Sketching can be fun and quick. Don't worry about mistakes it just takes lots of practice. This took me about 15 mins. Thats what I would recommend doing is rough sketches of faces like this over and over. ^^ I'd like you to sketch out Tomoe. Remember its just a quick sketch so it doesn't' have to be perfect!
