I like how I didn't even follow my outline when I drew the face...;orz.
Extra tips:
- Draw the outline (if on paper) EXTREMELY lightly. Then when you get to the drawing on top go as dark as you want. If you mess up a little keep drawing more lines until it looks better. Don't just stop after one wrong mark.
- Don't worry about being too exact. The lines don't have to be exactly half of each line etc. If if doesn't look right if you put the mouth down that low or if you but the nose up that high then change it how you like it. The outline is there to help you see where to go and what might go wrong! ;D
