Sorry if my pictures are fuzzy, but it is kind of hard to get great pictures with an ipod.
You can start with lines like these or you can skip this step. Personaly I skip this step, but if you are having trouble you can start here.
Now you smooth out the lines, and make them thick! ( or you start with nice, thick, smooth lines- as shown above)
Add a line that goes down and ends in a point. Also, you need a smooth line at the bottom.
Add a faint diamond shape like shown above, this is your guideline for the iris.
Harden the lines that fall inside of the other lines. Congradulations! You now have an iris!
Erase the rest of the diamond shape and add a little oval for a reflection.
Here is a hard part. You have to add a shape that looks somewhat like the shape shown above. You may like to look at some pictures online for help on that shape if it looks funny to you.
Now shade the eye! Leave the reflection white, make that funny shape gray, and color the rest black.
If you are doing this in color, the funny shape is the iris so you can give it some color!
Don't forget to give your eye a partner! I advise putting the eye you just drew on the right, but it's up to you! The next picture shows the eyes better though.
