Creating portraits on Illistrator

Illistrator:

To create this picture i took a picture of myself and imported it into Adobe Illustrator to make myself look as much like a cartoon as i can, i took my photo and outlined my different features such as: hair, face, body, lips, etc with the pen tool i joined the lines and outlined the different sections of my picture. By doing this i have then got all the different features to work with, with every time i outlined a different feature i created a new layer and by the end of it i had a substantial amount of layers with the different outlines. To make the picture look more natural i then click the layer with the direct selection tool in which allowed me to see and click each specific point as they all became obvious when layers are selected, after this i then choose convert tools which allows for the jagged edges to be smoothed out and the points to be manipulated and moved around for such things like hair, face, eyes to look a lot more natural and normal. After this i was then able to select different colours for the different parts of my picture, i did this easily as i have a layer for each little thing; by selecting the layer i was able to select what colour i would want it by clicking on 'fill' down the left hand side which showed the various colour options to pick from.
