draw animation- in purple clothes

I had up a pic like this before, and I will show you how I draw it! As a fact, I draw by watching the process of draw animation video from the YouTube.

sorry, I up the pics in a reverse turn. if you introduced in this post, please read it from the bottom.
draw the cloths using the base colour : purple. draw some shade of the neck and face .

then, draw a pic line on the edge, and draw the hair using black colourthe first step: draw the edge of it. It is the most difficult step!
